Solve all four for like Problem 3.Consider the function f(x, y) = In(x² + y?).a) Find the directional derivative of the function in the direction of the vector v = (1, 1).b) Consider the level curve f(x, y) = In(8). Determine the maximal value of the directional derivative at a point (x, y) onthis level curve.c) Geometrically, what direction vector produces the answer in part (b)? It may help to draw a picture.d) Now, determine a relationship between x and y for which the directional derivative in the direction of v is 0. Geometri-cally, why would we expect this answer?

This question is about gradients and directional derivatives. How can you tell the differences between these questions? Type 1: given that phi = x^2y^2z^2, find grad phi, grad phi at (-1,1,1) and a unit vector in this direction, the derivative of phi at (2,1,-1) in the direction of i and d = 3/5i + 4/5kThis question requires you to first find grad phi, plug in the coordinates and make a unit vector out of it, then multiply this unit vector by the two directions to get two solutions. Type 2: calculate the directional derivative of lamba(x) = x^2yz + 2xz^2 at the point (1,-2,1) in the direction of vector v=1/3(1,1,2) While, at first, it looks similar to the previous question, the working out is different. It requires you to find grad phi and sub in (1,-2,1). Then, you find the magnitude of the vector. You multiply grad phi at (1,-2,1) by the vector and divide all of that by the magnitude to give you the answer. I don't understand why it's different, Type 3: consider the scalar field phi…
