Question 2

The temperature in the xy-plane is a function  T(x, y). At the point  (a, b)  the directional derivative of  T  in the direction of the vector 3 i + 4 j  is 4 and the directional derivative in the direction of  5 i - 12 j is -2.  Find ∇T(a,b).
◦ (28 i + 37 j)
◦ (43 i - 17 j)
◦ (-53 i + 117 j)
◦ (68 i + 89 j)
◦ - (172 i + 89 j)
