Here you'll find the integration template.

Then, there's just to plug in the numbers. "x" is on the key right of the template key you just used..
But you have to hit the +/- key before the "x" key in order to get the desired result.

I entered the integral just fine, I meant I could not get a pretty equation on the forum here.
