# Math Help - Easy integral grrrrrrrrrr

1. ## Easy integral grrrrrrrrrr

$e^a^u \theta(u) du$ between t and 0

im getting confused by the theta

2. ## Re: Easy integral grrrrrrrrrr

The theta is comparable to the f in f(x). So to put the integral in similar terms, $\int{e^{au}\theta(u)du}$ is $\int{e^{ax}f(x)dx}$. Can you go from here?

it's going to be a never ending integral though
