1. The problem statement, all variables and given/known data Find integral of 4*e^(4x)*sin(e^(4x))dx 2. Relevant equations 3. The attempt at a solution Can I do this in this math problem I took the integral of 4e^(4x)*sin(e^(4x)) dx using substitution method. in the end I got e^(4x)*-cos*[1/e^(4x)] do the ex^4x just cancel out?
