Re: Analytical solution possible?


I tried this in Mathematica 9.0.1 and DO get the expected message 
Solve::ifun : Inverse functions are being used by Solve. . . and, 
furthermore, obtain a rather long solution that is expressed in terms of 
some InverseFunction expressions.

What version were you using?
