Hello,
Your answer is correct. However you explained the method of getting in wrong way (you flipped x and y!).
In fact, . That is, you find then you differentiate what you get with respect to y.
Hope that helps
Okay so I know how to get partial derivatives. One thing that I'm having trouble with is finding f_xy, because I'm not sure if I'm actually doing it correctly.
For example, lets say:
z=xy(5-x)(y-2)
f_x=(5-2x)y(y-2)
f_y=x(5-x)(2y-2)
to my understanding.... to get f_xy you have to take the partial derivative of y and then using that function now take it into respect of x.
So the answer i got was
f_xy=(5-2x)(2y-2)
