Question

\[\int\limits_{-1/2}^{1/2} \cos(2\pi t) e^{-jwt} dt \] I just got this on test, but unfortunately i could not solve it, i used the integration by parts twice but i did not get the solution. help guys ?

Answer 1

Call the given integral \(I\), then after integrating twice by parts you will get two equations in two variables one of which is \(I\). Solve for it.

Answer 2

well, I did not think about this I think you are right, i will try to solve it again.

Answer 3

Good luck.

Answer 4

thanks bro, i appreciate it.
