Question

Find the derivative : y=sin^3(4x^2)

Answer 1

chain rule. Know it?

Answer 2

yeah but how do i use chain rule here?

Answer 3

let 4x^2 = A, so you have sin^3(A), then find dy/dA and multiply it by dA/dx

Answer 4

would the answer be 24xsin^2(4x^2)cos(4x^2)

Answer 5

yeah. Good job.

Answer 6

i still dont get it, i just put down the answer from the back xD

Answer 7

okay, chill.

Answer 8

wait i get it, but shouldn't the answer be 24xsin^2(4x^2)cos^2(4x^2)?

Answer 9

no, just cos

Answer 10

thx, i get it but wouldnt the answer be 24xsin^2(4x^2)cos(4x^2)

Answer 11

i mean 24xsin^2(4x^2)cos^2(4x^2)

Answer 12

nvm..

Answer 13

you don't seem to get this stuff

Answer 14

no i get it nvm :P
