Question

Find the partial derivatives of the function
f(x,y)=(1x−1y)/
(−5x−6y)

Answer 1

\[f _{x}=1(-5x-6y)^{-1}-1(-5x-6y)^{-2}(-5)(1x-1y)\]

Answer 2

\[f _{y}=-1(-5x-6y)^{-1}-1(-5x-6y)^{-2}(-6)(1x+1y)\]

Answer 3

That came up incorrect the for F(y). The correct F(x) is -(11 y)/(5 x+6 y)^2 if this helps you solve for F(y)

Answer 4

sorry at the end of fy it should be (1x-1y) i put + by mistake

Answer 5

Thats correct, Thanks!
