A function f and a point P are given. Let 9 correspond to the direction of the directional derivative. Complete parts a. through e. 1. P(1/1₁ -√²) f(x,y)=In (1 +6x² +5y²), P a. Find the gradient and evaluate it at P. 4√2 The gradient at P is 12 b. Find the angles (with respect to the positive x-axis) between 0 and 2x associated with the directions of maximum increase, maximum decrease, and zero change. What angles are associated with the direction of maximum increase? (Type your answer in radians. Type an exact answer terms of Use a comma to separate answers as needed.)
