Write a python program which uses Method of Steepest Descent to find the absolute minimum of any function f(x,y) of two variables. Your code should be a function call of the form Steepest (To, num_iter), where To is the starting point for your iterative call and num_iter is the number of iterations performed. You can hard code the definition of your function. You will need to use SymPy for this exercise. In general, at any given step in the process, you may get more than one critical value for ox(t), so in your code you will need to decide which corresponds to the minimum. Now apply your code to the following function: f(x,y) = 2: 4xy2 + 46 The output should be a solution with reasonable accuracy. There are several absolute minima, so the answer you get depends on your choice of to
