Hi there. I came to join this forum to seek help, because I can't solve the following homework question: The solution to this can be split in 3 right? 1. the homogenous #1: Eq:= c*x' +k*x =0 Characteristic: c*r+k=0 --> r=-c/k Homogenious solution: y(x) = A*exp((-(c/k)*x)) initi. condit X(0) = 0 --> A=0 ?? Homogen sol = 0?? 2. part sol. 1: the left hand side is equal to fc sin (wt) 3. part sol. 2: the diract delta function. But I just can't figure out how to integrate the dirac delta function. I thought of using impartial integration but im not sure..... please help!
