For each function below find the requested

partial derivatives. Note that $f_{x}is$ equivalent $to$

del$\frac{f}{d}$elx.

$Iff(x,y)=x^{6}y+x^3+3$ then

$f_x=$

$f_y=$

$Iff(x,t)=ln(t)\sqrt[\phantom{2}]{x}$ then

$f_x=$

$f_t=\sqrt[\phantom{2}]{(2)}is$ entered

using "sqrt$(2)"f(x,y)=\frac{18x^6}{y^3}$ then

$f_x=$

$f_y=$

$Ifw(u,v)=\frac{e^v}{v^2+u^2}$ then

$w_u=$

$w_v=$

$Iff(x,y,z)=z{e}^{xyz}$ then

$f_x=$

$f_y=$

$f_z=$
