In polar coordinates a two-dimensional vector is given by its radius and angle (r, e). Write a user-defined MATLAB function that adds two vectors that are given in polar coordinates. For the function name and arguments, use
[r th] = AddVecPol (rl, thl, r2, th2),
where the input arguments are (r1, θ1) and (r2, θ2), and the output arguments are the radius and angle of the result. Use the function to carry out the following additions:
(a) r1 = (5, 23°), r2 = (12, 40°)
(b) r1 = (6, 80°), r2 = (15, 125°)
