    Thread moved to the homework forums. Welcome to the PF, mashjavad. Please tell us what you know already about integration. What learning resources do you have available?

    Hi mashjavad,

    Looks like integration by parts doesn't solve the integral. It takes the form (e^-x sin ax)/x. I used mathematical software to evaluate and obtained exponential integrals with complex numbers in the result. I tink this involves incomplete gamma functions or numerical methods of integration.

    Sorry couldn't help much.
