The height of a hill in feet is given by h (x, y) 30 (14 5x²2y² + 3xy + 30x 18y) Where x is the distance in miles east and y is the distance in miles north of your cabin. If you are at a point on the hill 1 mile north and 1 mile east of your cabin, what is the rate of change of the height of the hill (a) in a northerly direction and (b) in an easterly direction. =
