Hello, I want to calculate the integral(adsbygoogle = window.adsbygoogle || []).push({});

[tex]\int^{2\pi}_{0} \exp(i(k t + \cos(t+\delta)))dt[/tex]

where k and [tex]\delta[/tex] are integer and real numbers, respectivily.

I know with [tex]\delta[/tex]=0 the result is given in terms of Bessel functions, but I don't know what to do if [tex]\delta[/tex][tex]\neq[/tex]0.

Any help would be appreciate, thanks in advance.
