what did i do wrong..

Answer 1

hmm isnt missing the 1/2

Answer 2

\[y= \cos(\sqrt{\sin(\tan \pi x)} )\] you should add appropriate brackets first of all

Answer 3

hmm can you help me solve it

Answer 4

Yes

Answer 5

Note that it's a composite function inside the cosine so you have to apply chain rule, meaning take the derivative of cosine first

Answer 6

and go inwards

Answer 7

can u draw it lol

Answer 8

\[y' = -\sin(\sqrt{\sin(\tan \pi x)}) \times (\sqrt{\sin(\tan(\pi x)})'\]

Answer 9

your solution doesn't make much sense to me, you're either doing too many steps at once or skipping them

Answer 10

oh hmm i always get lost with this

Answer 11

but can u write it like this
