Question

find derivative of g(x)=2tan^3 (4piex)

Answer 1

what have you got so far?

Answer 2

i replaced the 4piex to u

Answer 3

oh yeah. sorry i forgot this part of derivatives.

Answer 4

try replacing tan(4 pi x) with u so you have 2(u)^3 then use the chain rule from there

Answer 5

ok i got: 1/2 x^2{(16-x^2)^-1/2(2x)}+(16-x^2)^-1/2 (x)

Answer 6

can you show me the steps you took to get that?

Answer 7

i did the product rule and chain

Answer 8

you dont have to use the product rule here

Answer 9

the first step is to differentiate 2(u)^3 with respect to u

Answer 10

ok i get that

Answer 11

what do you get?

Answer 12

1/2 x^2 (u)^1/2

Answer 13

to differentiate 2(u)^3 with respect to u, you just need to use the power rule so it becomes

6u^2

Answer 14

oops i did the wrong prob!!

Answer 15

oh so what is the problem you need to solve?

Answer 16

that same prob but i did the wrong work

Answer 17

ok so can you differentiate 2u^3?
