Please just Do problem 3 using fmincon . Dont need to do problem 2 l you will just need the polynomial from problem 2.

Problem 2) Unconstrained optimization of two variables 30 points Replace the polynomial function of Problem 1 with the following z = sin(x) + cos(y) With the limits 2 * pi and% y 2 * pi x a) Plot the function for the given ranges of x and y b) Starting at [x,y] = [5.5, 5.5], find the nearest minimum using fminune, stating the optimal values of x and y along with the optimal cost
