Question

Find the partial derivative of z=(xy)/((2x^2)-(4y^2))

Answer 1

wrt? x, y or both?

Answer 2

both

Answer 3

I did the quotient rule but it says I'm still wrong.

Answer 4

dz/dx = -(y (x^2+2 y^2))/(2 (x^2-2 y^2)^2)
dz/dy = (x (x^2+2 y^2))/(2 (x^2-2 y^2)^2)

Answer 5

o.O what did you do?
