, so you're left with:
Find the stationary points for the surface. And find the local and absolute maxima or minima for the following function.
Is there any stationary points for this surface?
Let z = f(x,y)
I found the
=
and
=
I'm supposed to equate the two equations to get the stationary points (X , Y) and substitute them into f(x,y) to get Z. But I could not since I could only get from the two equations and that's it.
How do I proceed? Did i do anything wrong?
Do you mean and ?
No, you do not "equate the two equations", you set each expression equal to 0.

Since an exponential is never 0, those are easy to solve.
I find 5 stationary points.
