Hi! I have a problem solving this integral.Could someone help me or give me an advice?
$\displaystyle
$$\displaystyle \int_{0}^{2\pi} cos(\theta)exp(a \cos(\theta))d\theta
$
Thankyou in advanced!
Hi! ,Thanks for replying!
Yes, i'm sure it's like that. I also tried with Mathematica,and it seems that there is no elemental solution,but for instance, the integral
$\displaystyle
\int exp(\cos(a\theta))d\theta
$
Can be expressed in terms of the modified bessel function of the first kind I0(x)
so i was wondering if i could do something like that...(my code is plenty of integrals so if i can avoid to compute any of them numerically it would be great)
