# Thread: Need help with a chain rule problem

1. ## Need help with a chain rule problem

ok so I have y=e^(2sin(2t)) and for y' I got y'=e^(2sin(2t))*(sin(2t)+2(cos(2t)(2)) but it says its incorrect and I swear to god I have NO CLUE how this is wrong.

What is the derivative of 2? Or any constant for that matter?

Your derivative is indeed wrong. If you show us your work, we'll tell you where you went wrong.

I just did explain what is wrong. It was in the application of the product rule (which was not necessary, but would not have been wrong if the derivative of 2 were calculated correctly).
