Homework Statement
e^(-2x)*sin(3x)dx
Homework Equations
using e^(ix)=cosx+isinx
The Attempt at a Solution
so i get e^(-2+i3)(x)
so then after i integrate i get (e^(-2+i3)(x))/(-2+i3) then i multiply by the conjegate to get the i out of the bottom then i multiply it by cos(3x)+isin(3x) then pick out the real part is this correct.
