plz do them all
(1 point) Find the directional derivative off(x,y) = sin(x + 2y) at the point (1,-2) in the direction θ = 3n4 The gradient of f is: Vf = -cos(5) Vf(1,-2)=( -cos(5) The directional derivative is: , 2cos(5) :1 point) Suppose that you are climbing a hill whose shape is given by z = 616-0.03x2-0.04y2, and that you are at the point(100, 20, 300) n which direction (unit vector) should you proceed initially in order to reach the top of the hill fastest? f you climb in that direction, at what angle above the horizontal will you be climbing initially (radian measure)? 11 point) Consider the function f (x, y) =-x2-2y2 Find the the directional derivative off at the point (-1,1) in the direction given by the angle θ = Find the unit vector which describes the direction in which f is increasing most rapidly at (-1, 1).
