Question

Find dy / dx by implicit differentiation.
9 (x^2)y + 8 (y^2)x = -1

Answer 1

Okay, what is :\[
\frac {d}{dx} 9x^2y
\]

Answer 2

We can start by using product rule: \[
\frac{d}{dx}9x^2y= \left(\frac{d}{dx}9x^2\right)\cdot y + 9x^2\cdot \left(\frac{d}{dx} y\right)
\]

Answer 3

Are you still stuck?

Answer 4

No i just made my first question and playing around with the website to figure it all out but thanks!

Answer 5

Oh, okay so you did figure out out then?
