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! 2I don't know if this helps

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
