Integration with hypergeometric function

Click For Summary

Discussion Overview

The discussion centers on the integration of the hypergeometric function _{2}F_{1}(B;C;D;Ex^{2})\,Ax, where x is the independent variable and A, B, C, D, and E are constants. Participants explore methods for integrating this function, considering both power series and alternative approaches.

Discussion Character

  • Exploratory
  • Mathematical reasoning

Main Points Raised

  • One participant asks how to integrate the hypergeometric function multiplied by Ax.
  • Another participant suggests expressing the hypergeometric function as a power series and inquires about integrating a power series.
  • A participant expresses familiarity with the power series method but seeks a simpler and more compact integration method.
  • It is noted that the hypergeometric function is defined as a power series, raising doubts about the feasibility of avoiding this method.
  • Concerns are raised regarding the power series being defined only for |x|<1, which may limit its applicability.
  • A participant provides a link to an external resource for integrating the function and suggests a change of variable, X=x², as a first step.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the best method for integration, with multiple approaches being discussed and no clear resolution on the preferred technique.

Contextual Notes

The discussion highlights limitations related to the convergence of the power series and the specific conditions under which it is defined.

How to integrate:

_{2}F_{1}(B;C;D;Ex^{2})\,Ax

where _{2}F_{1}(...) is the hypergeometric function, x is the independent variable and A, B, C, D, and E are constants.

Can you write {}_2F_1(B,C;D;Ex^2)Ax as a (power) series? Do you know how to integrate a power series?

I am familiar with the power series method but I am trying first to find a simpler and more compact method.

Since the hypergeometric function ##{}_2F_1## is defined as a power series, it is hard to imagine a solution that avoids it.
 
One problem with the power series is that it is defined only for |x|<1.
