Hey, could I get some guidance on how to do this question:

Integrate cos(x)sin(x)e^(cos(x))

I figure you'd also have to use some trig identities here, correct?

My first approach was:

let u = e^(cos(x))

so du/dx = -sin(x)e^cos(x)

let dv/dx = sin(x)cos(x) = 0.5sin(2x)

so v = -0.25cos(2x)

=> uv - integral of -0.25cos(2x)e^cos(x)

.. and yay, we're back to square one practically
