I have this equation here...

(x/3)e^(x^2)

I'm thinking I have to take this in parts, am I right?

since isn't integration by parts the anti - product rule? and I see two products of x in this...

or am I totally wrong?

if it IS integration by parts....

which do I choose for u and dv

I think I have u = (1/3)x

du = 1/3dx

dv = x^2

v = (1/3)x^3

Will this work? I need to know how to recognize between u-sub and integration by parts and WHAT to take...
