A happy heat-loving bug is wandering on a hot plate. The temperature at any point on the plate is given by
T(x, y) = 210e-(x^2/5)-(y^2/2)
If the bug is at the point P = (-3,3) and moving towards the point Q = (3,2), what is the rate of change in the temperature in the direction of its motion?
In what direction should the bug move from P for the temperature to increase the fastest?
What is the magnitude of the rate of change of temperature in that direction?
