Need help with Integration of a Cos function

Hi All,

Hoping someone can help me out with this problem.

I am trying to find the integral with respect to t of the following:

y = (u + at) * (cos(bt/(u+at)))

Any assistance would be greatly appreciated.

Thanks in advance.

;-)

Re: Need help with Integration of a Cos function

Throwing this to wolfram's mathematica integrator shows this to be a ridiculously difficult integration, perhaps there is a simple way but i have no idea to be honest

http://integrals.wolfram.com/index.jsp?expr=(u+%2B+ax)+*+(cos(bx%2F(u%2Bax)))&random=false
