Question

The temperature at a point (x,y,z) is given by

 
T(r, y, z) = 1500e
%3D
where T is measured in °C and r, y, and z in meters.
1. Find the rate of change of the temperature at the point P(2, –1,2) in the direction toward the point Q(3, –3, 3).
Answer: D f(2, –1, 2) =
PQ
2. In what direction does the temperature increase fastest at P?
Answer:
3. Find the maximum rate of increase at P.
