Question

Implicit Differentiation of
x^2-2xy+y^3=5

Answer 1

you use the product rule to derive -2xy to get -2y - 2xy'

Answer 2

2x+2y-2xy'+3y^2y' ?

Answer 3

so it should be

x^2-2xy+y^3=5

2x - 2y - 2xy' + 3y^2*y' = 0

solve for y'

Answer 4

-2y not +2y

Answer 5

tell me what you get for y'

Answer 6

(2x+2y)/(2x+3y^2)
?

Answer 7

close, but incorrect

Answer 8

one moment

Answer 9

ok

Answer 10

(2(y-x))/(3y^2 -2x)

Answer 11

that is the correct dy/dx expression

Answer 12

ah, thank you
