Answer 1

you can also write it \[(\cos(x))^2\]

Answer 2

so i can apply chain rule to it?

Answer 3

Yep

Answer 4

hey can I ask you another question?

Answer 5

fire away

Answer 6

how do I turn \[\sqrt{y}= x^{2}(x+7)\] into y=mx+b form?

Answer 7

well first I would distribute the \[x^2\] into the (x+7) then solve for y by squaring both sides.

Answer 8

my bad its : \[y^{2}= x^{2} (x+7)\]

Answer 9

well then distribute the \[x2^\]
then take the square root of both sides to solve for y. Remember when taking the square root you might need to account for the result being + or -

Answer 10

err
\[x^2\]
