How do you find the integral of e^(-x)sin(2x)dx using integration by parts? Here's my work: u = sin(2x) dv to be e^(-x)dx du = 2cos(2x)dx v =...

You need
to avoid the perpetual cycle, hence, you should use the following notation
dx


e^(-x) => du = -e^(-x)dx


Using the following formula yields:


vdu


You should solve the integral   using parts such
that:
