Question: the temperature at a point x y on a flat...
The temperature at a point (x, y) on a flat metal plate is given by T(x, y) = 76/(5 + x2 + y2), where T is measured in °C and x, y in meters. Find the rate of change of temperature with respect to distance at the point (3, 2) in the x-direction and the y-direction.
(a) the x-direction. °C/m
(b) the y-direction. °C/m
