Ctft of sin function

WebRecall that the integral of sine or cosine over an integer number of cycles is zero (it spends half the cycle above zero and half below, each at the same height, so the net area over a single cycle is exactly zero). So, in general, Euler’s formula plus this idea tells us, for any nonzero integer k, that: Z <2ˇ> ej!k= Z <2ˇ> cos(!k)d!+j Z ... Web3. Using the integral definition of the Fourier transform, find the CTFT of these functions.
