A B C D E F G H I J K L M N O P Q R S T U V W X Y Z
Let

$\displaystyle f(x,y)=sin(x^3-4xy^2). $

Evaluate

$\displaystyle f_x$    and $\displaystyle f_y $

at

$\displaystyle P_1=(0,1) , P_2=(1,\frac12)$    and $\displaystyle P_3=(\sqrt[3]{\pi},0).$


Solution:

  $ P_1$ $ P_2$ $ P_3$
$ f_x$ $ \cdot \sqrt[3]{\pi^2}$
$ f_y$
