Good morning,

I need help, I'm studying for my calculus final exam and I'm having some troubles solving some questions we had in previous test. Please, can anyone teach me how to solve these?

-----------------

1)For

z = ƒ (x,y) = √x

^{2}+ 3y (root)

verify Clairaut's Theorem (ƒ

_{xy}= ƒ_{yx}).---------------

2) Find all partial derivatives for

g(p,q,r) = p.cos(πpq+qr

^{2})^{ } (pi)

-------------------------

I would really appreciate your help.
