1. The problem statement, all variables and given/known data I need to find the fourier transform of v(t)=A*e(-t) such that t≥0. 2. Relevant equations ∫v(t)*e(-j*2*∏*f*t)dt,t,0,∞) 3. The attempt at a solution ∫v(t)*e(-j*2*∏*f*t)dt,t,0,∞)=A/(4*f2*∏2+1)-i*(2*A*f*∏)/(4*f2*∏2+1) the answer should be A/(1+i*2*∏*f). It seems like this problem should be straight forward so I'm wondering if I'm just missing an identity of some sort or something? This is actually only one part of the problem but I know how to get the rest of the answer once I get this part done.
