Suppose that g is a function of two independent variables that has continuous partial derivatives, and consider the points P(6,4), Q(10,4), R(6, 20) and S(17, 20). You are given that the directional derivative of g at P in direction PQ is 10, whilst the directional derivative of g at P in direction PR is 17. Find the directional derivative of g at P in direction PS.
