Hi there...i would very much like to know the analytical solution to the following exponential integral...

Exp[a*cos(b-c)] dc

where a and b are constants and cos is the cosine.

Thanks in advance,
Abel

I can only give you the definition of exponential integral because my knowlege on this topic is very limited.

Code:

    
         ∞    z^k                            1
Ei(z) =  ∑  (-----) + EULER_GAMMA_CONSTANT + -ln(z²)
        k=1   k.k!                           2

I don't know if this helps
