1. The problem statement, all variables and given/known data I'm supposed to be using the similarity theorem and the shift theorem to solve: cos(πx) / π(x-.5) has transform e^(-iπs)*Π(s) 2. Relevant equations similarity theorem f(ax) has transform (1/a)F(s/a) shift theorem f(x-a) has transform e^(-i2πas)F(s) 3. The attempt at a solution I don't know. cos(πx) has the impulse pair transform and the impulse pair function has cos(πs) transform. the only term that I can get is that the shift theorem will give me a e^(-iπs) because the 1/2 in the impulse function. I don't understand how to get the rect(s) term in the transform.
