Use Matlab

2.2 (20 points) Plot 8 figures in one window as 4 rows by 2 columns using subplot. Create array x to be from -n to a with increment 7/30. 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 5th figure is secant function, and the 6th figure is cosecant function, the 7th figure is the sum of sine and cosine, and the 8th 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
