Should be another pretty quick question, but I was given the following problem:
I understand that the derivative of the upper limit has to be used here, but I'm not to sure how it's supposed to be included. I thought [MATH]6x^2[/MATH] was supposed to be substituted in for [MATH]t[/MATH], and that you should multiply the whole thing by the derivative of [MATH]6x^2[/MATH], but I'm not sure if any of that's right. Any help would be appreciated.
