Chain rule 1 point possible (graded, results hidden) [SADT3] Suppose that the temperature in a given region is given by T(x, y) = 200xy(1 - 2x2 - y2). Suppose that you and your friend are at (1, 1). Suppose further that your friend is running along the x - driection initially and his speed is 3 meters per second. At what speed in meters per second must you move in the y - direction so that your friend's rate of change of temperature is the same as yours
