Find the direction in which the maximum rate of change occurs for the function x, y) = 2a: Si{a:y) at the point (4,1). Give your answer as a unit vector. Determine the gradient vector of a given real-valued function. Calculate the gradient of f(x, y) = xy at (x, y) = ( - 3, - 2). Vf( - 3, - 2) =\f\f4 4 Find the maximum rate of change of the function f{:::, y) = i at the point {3,2}. 1
