Description
|
|
•
|
The Gosper(T,x) command solves the problem of indefinite hyperexponential integration, that is, for the input hyperexponential function T of x, it constructs another hyperexponential function G of x such that , provided that such a G exists. Otherwise, the function returns the error message ``no polynomial solution found''.
