Question: Integrating an expression

Hello Everyone

 

I have an expression which I would like to integrate from x=0 to x=L. The expression is 

x1:=(sin(beta*x)*cos(m*Pi*x/L))/(1+alpha*x)

 

Here, beta, m, alpha are constant. However I want the result in terms of these quantities.

 

I will be grateful if you could help mw in this regard.

Thanks a lot.
