(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A: f(x,y) = e^(x+y) + cos(xy) / Ln(xy)

b: Sin(x) + cos(y) / 2x - 3y

2. Relevant equations

I'm not exactly sure if I'm doing this correctly, my book a little vague.

3. The attempt at a solution

for A I have when x = -1 and y = any real real number

for B I have when x = 3 and y = 2
