Hi,

I am bit confused by the step function. I was under the impression that it is basically a plug and chug but I think I am doing something wrong and need some clarification and some guidance.

Find the L[usub2(t)e^(-t)cos(3t)

So I get e^(-2s)L[e^(-2t-4)cos(3t+6)]

I am almost sure that this is wrong but really don't have any examples that are similar. Can someone please help me with this?
