Where Ln would be undefined is where you get a negative number? when it's zero it's ln(1)? And with B: I thought I answered where the difference is equal to zero with x = 3 and y = 2

So do you mean on say part A I'd have x = any negative number? I don't quite understand how I would lessen the restrictions on part B.

Homework Statement A: f(x,y) = e^(x+y) + cos(xy) / Ln(xy) b: Sin(x) + cos(y) / 2x - 3y Homework Equations I'm not exactly sure if I'm doing this correctly, my book a little vague. The Attempt at a Solution for A I have when x = -1 and y = any real real number for B I have...
