find all the critical points of the function

f(x,y) = (x-2y)e^(x^2-y^2)

and classify them as local maxima, local minima or saddle points.

How is this differentiated?

You need to use the product rule it is...

Differentiating with respect to x (finding ) make

Now apply

After this you need to differentiate for y. (finding )

Then solve for
