Question:

Starting from the initial trial solution (x1, x2) = (1, 1), interactively apply two iterations of the gradient search procedure to begin solving the following problem, and then apply the automatic routine for this procedure (with ϵ = 0.01).
Maximize f(x) = 4x1 x2 - 2x21 - 3x22.
Then solve ∆f(x) = 0 directly to obtain the exact solution.
