2.2 (20 points) Plot 8 figures in one window as 4 rows by 2 columns using subplot. Create array to be from * to * with increment w/30. The 1st figure is sine function, the 2nd figure is cosine function, the 3rd figure is tangent function, the 4th figure is cotangent function, the Sth figure is secant function, and the 6th figure is cosecant function, the 7th figure is the sum of sine and cosine, and the sth function is the product of sine and cosine. Place the title of function name on top of each figure. Save the MATLAB code into a script file named "hw0202.m". Show the script file and the resulting figure window
