I wish to integrate (4t-2)*e^(t^2-t).
du/dt = 4
dv/dt = ?
Am I even on the right track?

which we can write as:
(Do you see why this is a good substitution?)
What is the derivative of ?... is it somewhere in the integrand function?... Marry Christmas from Serbia
int t^2-t = 2t-1
Do I then use Integration by parts with dv = ?
No, you don't need integration by parts. Have you done substitutions (in integration) before?
Do you see how you can use this?
Thank you people - got it - U substitution.
2 int (2t-1)*e^(t^2-t) dt
= 2 int e^u du
= 2*e^u + c
= 2*e^(t^2-t) + c
Yes, that's correct.
