5.3 Partial Derivatives
www.personal.psu.edu › sxj937 › NotesThe parentheses are in place to indicate how I broke up the variables to take the derivatives. Now let’s calculate the last derivative, the partial derivative with respect to y. fzxy =(2z)(e xyz 2)+(2zy)(xz2e 2)+(2xy2z3)(xz2exyz2)+(4xyz3)(exyz2) After we simplify, we get the final answer fzxy =2zexyz 2 ⇥ 1+3xyz2 +x 2y z4 ⇤ Example 5.3.0.8 3.

Now, let’s do it the other way. We will now hold x x fixed and allow y y to vary. We can do this in a similar way.
