Question: Aymptotic expansion for hypergeometric function

I want to approximate the following hypergeometric function for large values of Y. The variables c and R are complex parameters.

hypergeom([-I*(c+sqrt(c^2-1)), I*(-c+sqrt(c^2-1))], [-I*(2*c+I), -I*(c+I+I*c/R)], exp(Y)*c/R)

 

I allready tried asympt(f,Y), but maple failed.

Please Wait...
