Last question on the tirgul

In the last question yesterday, where a thin ring has a decaying current and we are to compute the field, we where showed to solve the integral for since the one for
\( \hat{y} \)
is odd and equals zero.
How is the integral done?
I got something similar to:

\( \vec{A} = \frac{I_0 R}{rc} \int_{0}^{2\pi} e^{-\frac { \left(t-\frac{r}{c} +\frac{ sin\theta}{c}\cos \left(\phi - \phi '\right) \right)^2 }{2\tau ^2} } \cos{\phi '}d\phi ' \hat{y} \)
