Hi i know this is the wrong forum but i need help!!!

I have a question I don’t even know where to start with, it is as follows:

Given the integral between 0 and infinity of sin ax / sinh bx = (pie/2b) * tanh * ((pie *a)/ 2b ) calculate…

The integral between 0 and infinity of cos ax / sinh bx dx

I mean what should I do can I just swap the cos ax for a relationship with sin ax if so what??

Or do I just perform the integration, how would I do this and what is the answer??

Thanks

why don't you ask the Maths Department instead of the General Chat Department?
i would like to help you with the Maths bit, but i don't think that's my level (yet)...
