: Dear math folks:

: Can someone give me any comments or suggestions to solve

: the following symbolic integral?

: /

: | 1

: | ------------------------ dy

: | 1+k*y*(1-exp(-(y/A)^2))

: /

: in which 'A' and 'k' both are any positive constants.

: I have tried several ways,for example,Maple, Mathcad, Mathematica.

: But found no solutions. I need your help!

Try one of the "old fashioned" ways: integration by

differentiation under the integral sign. For details,

see, for example, "Advanced Calculus" by Woods.
