Question

usa the chain rule to find the derivative of h(x)=sin2xcos2x

Answer 1

chain rule is like a cake, it has layers

Answer 2

wellll i really need to learn how to make this cake. because its confusing to me.

Answer 3

So like one of the previous ones sandy, we have the product rule.
You can eliminate the need for product rule if you remember your double angle formula for sine though! :)

Answer 4

so for the product rule would u be sin2x and v would be cos2x?

Answer 5

Mhm :3

Answer 6

sooo i got sin2x(-2sin(2x))+cos2x(2cos(2x)) ?
haha i feel like i did that wrong...

Answer 7

Hmmm let's see :)

Answer 8

Oh, looks like you did it correctly! :) I just got confused because you do it in the reverse order that I usually do hehe
