Question

Hi there, here is my question: x = (tan^2)(y^-1)

Answer 1

y=224

Answer 2

What to do with it?

Answer 3

sorry, differentiate

Answer 4

in respect to what?

Answer 5

in respect to dy/dx, right?

Answer 6

Well, this is what I'm asking, Taking derivative in respect to x? \(\dfrac{d}{dx}\)?

Answer 7

yes

Answer 8

I know that y = arctan(x) and x = tan(y) but this is different

Answer 9

Just making sure. This is implicit differentiation.

Just use chain rule then isolate y' (aka \(\dfrac{dy}{dx}\)). You can do it, right?

Answer 10

let me try that thanks
