The temperature at a point $(x,y)$ en a flat metal plate is given by $7(x,y)=\frac{40}{(4x^2{y}^2{)}^2},=$lere $T$ is meanured in $AC$ and $x,y$ in meters. Find the rate of change of temperature $($in $"$C$/$m$)$ with respect to distance at tie pelnt $(1,2)$ in the $x-$drection and the $r-$direction.

$($a$)$ the $x-$direction

$4\frac{c}{m}$

$($b$)$ the $y-$direction
