I started re-reading KA Strouds Engineering Mathematics and have been using SMath to work examples. Please see the attached file. If I could get some comments on the various methods I attempted to use I would appreciate.
Thx
Joe

1 & 2 are asymptotic => NO X crossing abscissa
3. one crossing point
4. solve for g(x) instead of g(u)

Forgot to mention - you have given me a good rule and graphical method to determine suitableness of solve function.
Thanks
