Question

How to integrate 3 functions?

Answer 1

Find \[\int\limits_{}^{} (-11e^{-t^{3}} * (\sin(x))^{4} d/dx) d/dx\]

Answer 2

Oops It's -11e^x^3

Answer 3

But I did find the derivative inside the integral which is... \[-44e^{-t^{3}} \sin^{3} x \cos(x)\]

Answer 4

And then when you simplify, you get... \[-44 \int\limits_{}^{} e^{-x^{3}} \sin^{3} x \cos x dx\]

Answer 5

^This is the step I'm stuck on...

Answer 6

Hey take a screenshot of actual problem and attach if psble

Answer 7

Sure!

Answer 8

you are integrating a derivative here.

Answer 9

Yes but when you see my work above ^ we end up with 3 functions inside the integral! :)

Answer 10

don't you see the integral and derivative kill each other out leaving you with the function inside

so you don't have to do any work
