Just wondering if you could help me integrate the following:

[(cosh (x^0.5)) / (x^0.5)] dx

with respect to x

cheers

Thanks for your help - would you also possibly be able to guide me through this one too.... I'm trying to teach myself hyperbolic integration for fun, but the examples in my textbook are pretty poor...

Integrate: 2x((x^2)+1)^23) dx

Thanks very much for all of your help - March 6th 2008, 08:44 PMmr fantastic
