The temperature at a point (x, y) is T(x, y), measured in degrees Celsius. A bug crawls so that its position after t seconds is given by x = √1 + t , y = 2 + 1/3 t, where x and y are measured in centimeters. The temperature function satisfies Tx(2, 3) = 4 and T_y(2, 3) = 3. How fast is the temperature rising on the bug’s path after 3 seconds?
