The temperature at a point
(x, y, z)
is given by
t(x, y, z) = 300e−x2 − 3y2 − 7z2
where t is measured in °c and
x, y, z
in meters.
(a) find the rate of change of temperature at the point
p(2, −1, 3)
in the direction towards the point
(5, −3, 4).
°c/m
(b) in which direction does the temperature increase fastest at p?
(c) find the maximum rate of increase at p.
