Evaluate fx(x,y) and fy(x,y)at the indicated point.
\[\frac{\delta f}{\delta x} = 3x^2 -3 \] \[ f_x(-1,3) = 3(-1)^2 - 3 = 0\]
\[\frac{\delta f}{\delta y} = 2y^ -6 \]
\[ f_y(-1,3) = 2(3) - 6 = 0\]
find fx, fy, fxx, fyy, fxy and fyx.
\[ f(x,y) = \frac {x} {y} \]
\[f_x = \frac {1} {y} \] \[ f_y = \frac {-x}{y^2} \]
\[ f_{xx} = 0 \] \[ f_{yy} = \frac {-2x}{y^3} \]
\[ f_{xy} = \frac {-1}{y^2} \]
\[ f_{yx} = \frac {-1}{y^2} \]
