Summary

01 Gamma Function & Digamma Function

Although the factorial n! and the harmonic number are usuallydefined for a natural

number, if a gamma function and a digamma function are used, these can be defined for the real number p. That is,

The former is convenient to express the coefficient of the higher order primitive or derivative of a power function, and the

latter is indispensable to non-integer order calculus of the logarithmic function.

Although some formulas about these functions are described here, the following two formulas proved in Section 3 are

especially important. That is, when ,

These show that the ratios of the singular points of or reduce to integers or its reciprocals. The former is

necessary to express the higher order derivative of fractional functions, and the latter is required for the super calculus

of a logarithmic function.

02 Multifactorial

The relational expression of multifactorial and the gamma function is shown here.

For instance, in case of double factorial,

These are used to express the half-integration of a integer-power function later.

Moreover, we obtain the following Maclaurin expansions as by-products.

03 Generalized Multinomial Theorem

First, the binomial theorem and a generalized binomial theorem are mentioned. The Leibniz rule and the Leibniz rule

about super-differentiation are expressed just like these later.

Next, multinomial thorem and generalized multinomial thorem are shown as follows.

Higher order calculus of the product of many functions and super order calculus of the product of many functions are

expressed just like these later.

What should be paid attention here are the following property of generalized binomial coefficients.

That is, once generalized binomial coefficients were used, the upper limit of should be . Therefore, when n is

a natural number and p is a real number, the following holds in most cases.

When the original coefficient is not binomial coefficient e.g. 1 ,

Although is difficult, is satisfactory. What enables super calculus in this text

is just this property of the generalized binomial coefficient. Newton is great!

(1) Definitions and Notations

The 1st order primitive function of f(x) is usually denoted F(x). However, such a notation is unsuitable for the

description of the 2nd or more order primitive functions. Then, denote the each order

primitive functions of f(x) in this text. Here, for example, when f(x)=sin x, might mean -cos x or

might mean -cos x+ c. Which it means follows the definition at that time.

Furthermore, each order integrals of f(x) are denoted as follows.

And these are called higher integral with variable lower limits . On the other hand,

are called higher integral with a fixed lower limit.

(2) Fundamental Theorem of Higher Integral

There is Fundamental Theorem of Calculus for the 1st order integral. The same theorem holds for the higher order

integral.

Theorem 4.1.3

Let be continuous functions defined on a closed interval I and be the arbitrary

primitive function of . Then the following expression holds for .

Especially, when ,

(3) Lineal and Collateral

We call Constant-of-integration Polynomial the 2nd term of the right sides of these. And when Constant-of-integration

Polynomial is 0, we call the left side Lineal Higher Integral and we call Lineal Higher Primitive Function.

Oppositely, when Constant-of-integration Polynomial is not 0, we call the left side Collateral Higher Integral and we

call the right side Collateral Higher Primitive Function.

For example,

Furthermore, from Theorem 4.1.3, we see that must be all zeros of in order for the

higher integral of f(x) to be lineal.

(4) Higher Integral and Reimann-Liouville Integral

The higher integral with a fixed lower limit reduce to the 1st order integral which called Reimann-Liouville Integral.

Theorem 4.2.1 ( Cauchy formula for repeated integration )

When f(x) is continuously integrable function and denotes a gamma function ,

Reimann-Liouville Integral of the right side is important. However, in the higher integral, since the left side itself has

an operation functions, the right side is not indispensable.

By the way, replacing the left side in Theorem 4.1.3 for Reimann-Liouville Integral and shifting the index by -n,

we obtain the following.

This is the Taylor expansion of f(x) around a. And Reimann-Liouville Integral of is the remainder term called

Bernoulli form

(5) Higher Integrals of Elementary Functions.

When m is a natural number, the 2nd order integral of becomes as follows.

Then, when is a positive number, it is as follows.

Here, can be expressed by gamma function . Thus

By such an easy calculation, we obtain the following expressions for elementary functions. Where, denote the

ceiling function and the floor function respectively.

(6) Termwise Higher Integral and Taylor series of higher primitive function

Theorem 4.6.1

Let be continuous functions defined on [a,b] and be the arbitrary primitive function

of . At this time, if f(x) can be expanded to the Taylor series around a, the following expressions hold for

.

This expression shows that the Taylor series of consists of the constant-of-integration polynomial and the

termwise higher integral of f(x). The following can be said from this.

(1) A termwise higher integral with a fixed lower limit is collateral generally.

(2) It is the following case that a termwise higher integral with a fixed lower limit is lineal.

For example,

is collateral higher integral.

is lineal higher integral.

Next, the following is obtained from the Taylor series of the higher integral of log x.

Example

In this chapter, for the function which second or more order integral cannot be expressed with the elementary functions

among trigonometric functions and hyperbolic functions, we integrate the series expansion of these function termwise

and obtain the following expressions. Where, denote the ceiling function and the floor function respectively. And

Bernoulli Numbers and Euler Numbers are as follows.

(1) Taylor Series

(2) Fourier Series

(3) Riemann Odd Zeta & Dirichlet Odd Eta

Comparing Taylor series and Fourier series, we obtain Riemann Odd Zeta and Dirichlet Odd Eta. For example,

Here, we integrate the series of an inverse trigonometric function or an inverse hyperbolic function term by term.

Then, we obtain formulas simpler than what were obtained in "04 HIgher Integral". Moreover, both are compared and

we obtain various by-products.

07 Super Integral (Non-integer order Integral)

It is which extended the domain of index j of to the real number interval [0,p] from the natural

number interval [1,m]. And it is which extended the domain of index k of to the real number

interval [0,q] from the natural number interval [1,n]. It is called analytic continuation to extend the domain

generaly. Although usually analytic continuation is used for extending the domain of a function, it can be used also

for extending the domain of the index of a operator. Here, extending the domain of the index of the integration operator,

we obtain Super Integral (Non-integer order Integral ).

(1) Definitions and Notations

denotes the non-integer order primitive function of f(x). And we call this SuperPrimitive Function of

f(x). Since there is a super primitive function innumerably, which means follows the definition at that time.

We call it Super Integral to integrate a function f with respect to an independent variable x from a(0) to a(p)

continuously. And it is described as follows.

And

when , we call it super integral with a fixed lower limit,

when , we call it super integral with variable lower limits.

(2) Fundamental Theorem of Super Integral

Let be an continuous function on the closed interval I and be arbitrary the r-th order primitive

function of f. And let a(r) be a continuous function on the closed interval [0,p].

Then the following expression holds for .

Especially, when ,

(3) Lineal and Collateral

We call Constant-of-integration Function the 2nd term of the right sides of these.

And when Constant-of-integration Function is 0, we call the left side Lineal Super Integral . and we call

Lineal Super Primitive Function.

Oppositely, when Constant-of-integration Function is not 0, we call the left side Collateral Super Integral and we call

the right side Collateral Super Primitive Function.

For example,

(4) Super Integral and Reimann-Liouville Integral

The super integral with a fixed lower limit reduce to the 1st order integral which called Reimann-Liouville Integral.

This is what extended the parameter n to the real number in Cauchy formula for repeated integration. Since the left

side has lost the operating function, Reimann-Liouville Integral of the right side is very important. All the super integral

with a fixed lower limit can be verified numerically by this. On the other hand, since the super integral with variable

lower limits cannot apply Reimann-Liouville Integral, the verification is vary difficult.

(5) Fractional Integral & Super Integral

In traditional Fractional Integral, the super primitive function is drawn from Riemann-Liouville Integral.

For example, in the case of , it is as follws.

Let

Then

We find out that this is a convolution . Then we take the Laplace transform of

Finally, taking the inverse Laplace transform, we obtain .

Because the technique of Fractional Integral is difficult like this, it is more difficult to obtain the super primitive

function of log x by this technique.

Above all, the problem is that Fractional Integral cannot treat the lineal non-integer order integral such as sin x.

Because Riemann-Liouville Integral cannot be applied to the integral with variable lower limets.

On the other hand, in Super Integral that I advocates, first of all, we obtain the following higher integral.

And replacing the index of the integration operator n with a real number p, we obtain the following very easily.

Furthermore, performing the higher integral with variable lower limits and replacing the index of the integration operator

with a real number, we can obtain the super integral such as sin x easily.

of f(x)..

Moreover, we call it Higher Differentiation to differentiate a function f with respect to an independent variable x

repeatedly. And it is described as follows.

(2) Fundamental Theorem of Higher Differentiation

The following theorem holds from Theorem 4.1.3 .

When are continuous functions on a closed interval I and are the rth derivative functions of f,

the following expression holds for .

This theorem guarantees that only the lineal exists in the higher differentiation.

(3) Higher Derivative of Elementary Functions

When m is a natural number, the 2nd order derivative of becomes as follows.

Then, when is a positive number, it is as follows.

Here, can be expressed by gamma function . Thus

By such an easy calculation, we obtain the following expressions for elementary functions. Where, denote the

ceiling function and the floor function respectively.

Example

In this chapter, for the function which second or more order integral cannot be expressed with the elementary functions

among trigonometric functions and hyperbolic functions, we differentiate the series expansion of these function termwise

and obtain the following expressions. Where, denote the ceiling function and the floor function respectively. And

Bernoulli Numbers and Euler Numbers are as follows.

(1) Taylor Series

(2) Fourier Series

(3) Dirichlet Odd Eta (minus) & Even Beta (minus)

Comparing Taylor series and Fourier series, we obtain Dirichlet Odd Eta (minus) and Even Beta (minus) .

(4) Other by-products

Among trigonometric functions and hyperbolic functions, there are functions that it is difficult to obtain the general

form of the second or more order derivative. In this chapter, we differentiate the series expansion of these functions

termwise and obtain the following expressions. Where, denote the ceiling function and the floor function

respectively.

(1) Taylor Series

(4) By-Products

Example

12 Super Derivative (Non-integer times Derivative)

Here, extending the domain of the index function of a differenciation oprator, we obtain Super Derivative (non-integer

order derivative).

(1) Definitions and Notations

denotes the non-integer order derivative function of f(x). And we call this Super Derivaive of f(x).

Since there is a super derivative function innumerably, which means follows the definition at that time.

We call it Super Differentiation to differentiate a function f with respect to an independent variable continuously.

And it is described as follows.

(2) Fundamental Theorem of Super Differentiation

Let be an continuous function on the closed interval I and be arbitrary the r-th order derivative

function of f. And let a(r) be a continuous function on the closed interval [0, p].

Then the following expression holds for .

Especially, when ,

(3) Lineal and Collateral

We call the 2nd term of the right sides of these Constant-of-differentiation Function.

And when Constant-of-differentiation Function is 0, we call the left side Lineal Super Differentiation and we call

Lineal Super Derivaive Function .

Oppositely, when Constant-of-differentiation Function is not 0, we call the left side Collateral Super Differentiation and

we call the right side Collateral Super Derivaive Function.

For example,

when ,

when

As seen from this example, the lineal and the collateral exist in the super differentiation unlike the higher differenciation

(4) Riemann-Liouville Differintegral

When the super integral of f(x) is the one with a fixed lower limit, the super derivative of f(x) is obtained by

the following formula. In this formula, the n th order differenciation is subtracted from the n-p th order integration

and the p th order derivative is obtained. Then, this formula is called Riemann-Liouville Differintegral.

Since the left side has lost the operating function, Reimann-Liouville Differintegral of the right side is very important.

(5) Fractional Derivative & Super Derivative

In traditional Fractional Derivative, the super derivative is drawn from Riemann-Liouville Differintegral.

For example, in the case of f(x)= log x, it is as follws.

Long calculation continues.

Because the technique of Fractional Derivative is difficult like this, it is unknown in whether the case of p =1/3 is

calculable in this way.

Also, it is the same as the case of super integral that Riemann-Liouville Differintegral cannot be applied to the non-

integer order derivative such as sin x.

On the other hand, in Super Derivative that I advocates, first of all, we obtain the following higher derivative.

Since differentiation is the reverse operation of integration, reversing the sign of the indexof the integration operator,

we obtain the following immediately.

Substituting p = 1/2 for this,

Thus, we obtain the desired super derivative very easily.

By the way, when p = 2, according to the formulas

it is as follows.

Furthermore, in a similar way, we can obtain the super derivative such as sin x easily.

22 Higher Derivative of Composition

22.1 Formulas of Higher Derivative of Composition

About the formula of the higher derivative of composition, the following formula was shown by Faà di Bruno about 150

years ago.

Formula 22.1.1 ( Faà di Bruno )

Let are non-negative integers. Let are derivative functions and are

the 2nd kind of Bell polynomials such that

Then, the higher derivative function with respect to x of the composition g{f(x)} is expressed as follows.

Next, the algorithm that generates without an omission is shown. And the derivatives up to

the 8 th order of z= g{f(x)} are calculated using this.

Next, trying the higher differentiation of some compositions, we obtain the following formulas.

Even if the algorithm above is used, it is not so easy to obtain .

However, when the core function f(x)is the 1st degree, it becomes remarkably easy.

Formula 22.1.3

When , if f(x) is the 1st degree, the higher derivative function

with respect to x of the composition g{f(x)} is expressed as follows.

And, this can be easily enhanced to the super-differentiation in this case. That is, the following expression holds

for p>0 . This is the grounds for which we have used "Linear form" since "12 Super Deribative" as a fait accompli .

23 Higher Integral of Composition

Formula 23.1.1

Let be the lineal higher primitive function of g(f) and are the functions of f such that

Let are the polynomials such taht

And let are the zeros of the lineal higher primitive functions of g{f(x)} , gh respectively.

Then, the lineal higher integral with respect to x of the composition g{f(x)} is expressed as follows.

(n-fold nest)

If it writes down up to the 3rd order without using , it is s follows.

Next, trying the higher integration of some compositions, we obtain the following formulas

Formula 23.1.1 is so complicated and is not applicable to any composition. The 1st, the inverse function of the core

function must be known. The 2nd, the higher primitive function of the enclosing function g(f) must have the property

such as . Considering these, there are not many compositions that Formula 23.1.1 is applicable.

However, when the core function f(x) is the 1st degree, it becomes remarkably easy.

Formula 23.1.2

When f(x)= cx+d,

And, this can be easily enhanced to the super integral in this case. That is, the following expression holds for p>0.

This is the grounds for which we have used "Linear form" since "07 Super Integral" as a fait accompli.
