Homework Statement
Took a test today, one question I am not sure I got right.
[itex]\int_{0}^{\infty} te^{-at}dt[/itex], when a>0
Homework Equations
The Attempt at a Solution
I set let infinity be b, then took the limit as b went to infinity of the integral with new bounds from 0 to b. My solution claimed that it converges to 1/a^2. Is this correct or should I expect to miss that question?
