Definite Integrals using Orthogonality and Integral Transforms [PDF]

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2012
We obtain definite integrals for products of associated Legendre functions with Bessel functions, associated Legendre functions, and Chebyshev polynomials of the first kind using orthogonality and integral transforms.

A Note on Some Definite Integrals of Arthur Erdélyi and George Watson

open access: yesMathematics, 2021
This manuscript concerns two definite integrals that could be connected to the Bose-Einstein and the Fermi-Dirac functions in the integrands, separately, with numerators slightly modified with a difference in two expressions that contain the Fourier ...

Fractional Definite Integral

open access: yesFractal and Fractional, 2017
This paper proposes the definition of fractional definite integral and analyses the corresponding fundamental theorem of fractional calculus. In this context, we studied the relevant properties of the fractional derivatives that lead to such a definition.

Integrals [PDF]

open access: yes, 2023
After reading this chapter you know: what an integral is, what definite and indefinite integrals are, what an anti-derivative is and how it is related to the indefinite integral, what the area under a curve is and how it is related to the definite ...

A Comprehensive Definition for Integrative Oncology [PDF]

open access: yesJNCI Monographs, 2017
Background: Integrative oncology, which is generally understood to refer to the use of a combination of complementary medicine therapies in conjunction with conventional cancer treatments, has been defined in different ways, but there is no widely accepted definition.We sought to develop and establish a consensus for a comprehensive definition of the ...

On some summation formulas

open access: yesDemonstratio Mathematica, 2022
In this note, we derive a finite summation formula and an infinite summation formula involving Harmonic numbers of order up to some order by means of several definite integrals.

Some intriguing definite integrals [PDF]

open access: yes, 1999
We calculate some definite integrals which (up to now) computer algebra systems like Maple or Mathematica are unable to evaluate. The first one is a simply looking integral involving cos and log, the others are some integrals containing polylogarithmic ...

Simultaneous Contour Method of a Trigonometric Integral by Prudnikov et al.

open access: yesMathematics, 2021
In this present work we derive, evaluate and produce a table of definite integrals involving logarithmic and exponential functions. Some of the closed form solutions derived are expressed in terms of elementary or transcendental functions.

Calculation of integrals in MathPartner

open access: yesDiscrete and Continuous Models and Applied Computational Science, 2021
We present the possibilities provided by the MathPartner service of calculating definite and indefinite integrals. MathPartner contains software implementation of the Risch algorithm and provides users with the ability to compute antiderivatives for ...

Further Equivalent Binomial Sums

open access: yesComptes Rendus. Mathématique, 2021
Five binomial sums are extended by a free parameter $m$, that are shown, through the generating function method, to have the same value. These sums generalize the ones by Ruehr (1980), who discovered them in the study of two unexpected equalities between
