The temperature at any point (x, y) in a steel plate is T = 500 - 0.5x2 - 1.2y2, where x and y are measured in meters. At the point (10, 3), find the rates of change of the temperature with respect to the distances moved along the plate in the directions of the x- and y-axes. (10, 3) = ax °/m °/m (10, 3) = ду
