You are skiing on a mountain whose elevation in kilometers is given by Etna} = E I: \"a\" 1where {any} is your position on the mountain and :r. and y are also in kilometers. Suppose you are at position {1, 1]. [a] 1What direction from the point [1, 1] gives the direction of steepest decent? Your answer should be a 2-D vector. [h] 1What is your rate-ofchange of elevation if you ski in this direction? {This is a 'rise over run:r rate of change: change in elevation divided by change in horizontal position.) [c] hi 1ivhat direction from the point [11 1] (eiquessed as a 2].] vector} should you point your skis so that the rate-of-change in elevation is [1
