5. (10 pts) You are making fried rice in a eastiron pan, and in coordinates where the center of your 1 (:172 + y2)1/2 degrees pan is (mmyo) = (0,0), the temperature of a point on your pan is T(.'r,y) = oelsius. (a) Calculate the gradient of the temperature of your pan (b) At the point (any) = (1,1) nd a. (normalized) direction vector where your T(:c,y) remains constant moving a point from (1, 1) in that direction
