 Dear math folks:
      Can anyone give me comments or suggestion 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,
 But found no solutions. I need your help!
 Thank you in advance!

 Leevis
