Expert Solution
Step 1: Formula used and given.

Note: We'll answer the first question since the exact one wasn't specified. Please submit a new question specifying the one you'd like answered.

Formula: If the function f is differentiable at x, then the directional derivative exists along any vector v, and it is given by,

∇vf(x)=v·∇f(x)

Given: f(u)=aTu=∑i=1daiui, for a, u∈ℝd.
