- Homework Statement
- These types of problems have been a mystery to me.

According to wolfram this ends in the function ## _2F1(a,b;c;z) ##

but how?

- Relevant Equations
- ## _2F1(a,b;c;z)=\sum _{n=0}^∞\frac{\left(a\right)_n\left(b\right)_n}{\left(c\right)_n}=1+\frac{abz}{c1!}+\frac{a\left(a+1\right)b\left(b+1\right)z^2}{c\left(c+1\right)2!}+... ##

I also don't understand how to get the descending factorials for this hypergeometric series, I also know that there is another way to write it with gamma functions, but in any case how am I supposed to do this?

If I write it as a general term, wolfram will give me the result

which leaves me even more puzzled since I do not understand where a, b and c are

Could you tell me where to start? or where you should keep looking for information.
