Warning: Explicit integral could not be found.

Hi,

I am trying to solve the below integral but getting the error: Warning: Explicit integral could not be found.

Can you please help?

syms k m A B R

int(exp((2*R*atan((B + A*tan((m*x)/2))/(A^2 - B^2)^(1/2)))/(m*(A^2 - B^2)^(1/2)))*sin(m*x), x)

Do you have particular reason to expect that it has a closed-form integral?

I have done more exploration, and I still cannot see any reason why one might expect the result to be a closed form.
