Answer 1

Hey do you know implicit differentiation?

Answer 2

That is what i got so far

Answer 3

Your notation is a bit confusing, it's \[\frac{ dy }{ dx }\]

Answer 4

derivative of a constant is 0... don't forget that!

Answer 5

also, you had an error in taking another derivative... look it over and be careful!

Answer 6

In any case, \[4-xy=y^3\] so you have the right idea, we do apply product rule, we get \[-y-x \frac{ dy }{ dx } = 3y^2 \frac{ dy }{ dx }\] right?

Answer 7

Right my mistake

Answer 8

Simply solve for dy/dx now :)

Answer 9

so it would then give you -y = -x dy/dx + 3y^2 dy/dx = -y/-x+3y^2

Answer 10

Careful with the signs

Answer 11

\[-y = 3y^2\frac{ dy }{ dx }+x \frac{ dy }{ dx }\] right?

Answer 12

crap right

Answer 13

Wait are you sure.

Answer 14

I thought it would be adding x

Answer 15

I'm not sure what you mean, can you please show it

Answer 16

at the very beginning its -(1)(y) + x dy/dx

Answer 17

Oh no no. Ignore me sorry got that wrong. Youre right. So then i got the answer of -y/x+3y^2

Answer 18

Perfect! :)

Answer 19

\[\frac{ dy }{ dx } = - \frac{ y }{ x+3y^2 }\]

Answer 20

Thank you!!! can you help me with another?

Answer 21

Hey, sure I can try
