Its all the same question even though its split into different parts. MATLAB is a pain the butt.

Exercise 1: Use MATLAB to plot the graphs of each of the following. Then determine what interval for t is needed in order to trace the entire graph only once. (Use subplot(2,2,1) through subplot(2,2,3) to get the three graphs onto one wi a.) Interval for t in order to trace r4cos(2t only once: Select exactly one of the choices. [0,x/3) b.1 interval for t in order to trace r cos(5t) only once: elect exactly one of the choices. [O,z/2] [o,21] c. interval for in order to trace r sin t/2) only once Select exactly one of the choices. O [0,41] d.) Submit a print-out of your graphs Upload your image flle here.
