Absolutely, no late submission is accepted. Write the answers in your own words individually. Any plagiarism will post a “ZERO” score or cause a “FAIL” grade. 6.1 (35 points) Write a function to_polar that accepts a complex number c, and returns two output arguments containing the magnitude mag and angle theta of the complex number. The output angle should be in degrees. The error message must be displayed when the number of input parameters is not equal to one. (a) Show the Matlab function. (b) Test the function by using: [a b]=to_polar(3+i*4). Answer: (a) function [a b]=to_polar(c) a=abs(c); b=angle(c)*180/pi; (b) >> [a b]=to_polar(3+i*4) a = 5 b = 53.1301 6.2 (35 points) Suppose that George, Sam, Betty, Charlie, and Suzie contributed \$25, \$15, \$10, \$5,
