Homework Statement Find integral of 4*e^(4x)*sin(e^(4x))dx Homework EquationsThe 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?

So I was suppose to subtract the vector components. I should have said Ax-Bx=Rx and Ay-By=Ry. Thank you very much
