what is the Matlab code of the two functions, I want to plot them in Matlab m,n vary from -50 to 50 c. (7%) fam, n) sin m) cos n), where m and n vary from d. (7%) f(x, y) sin (r) cos y), where x and y vary from Solution t = 0:0.01:(2*pi); x = cos(t); y = sin(t); plot(t,x,\'k\'); hold on; plot(t,y,\'r-.\'); axis([0 2*pi -1.5 1.5]) legend(\'cos(t)\',\'sin(t)\',\'Location\',\'.
