Write the Matlab code for the following.

4. (14. 15.09) Program to plot the following graphics The requirements are as follows: 1) Divide the plotting window into upper and lower two sub areas 2) The Abscissa ranges of the upper graphic is (0.21), the Abscissa ranges of the lower graphic is 10. #the ordinate ranges of the upper and lower graphics are all (-1,1] 3) The sine function graphic is marked with a black solid line and the Asterisk is selected as its identification. The cosine function graphic is marked with a red dot dash line, and the circle is selected as its identification: 4) The titles of the two graphics are 'graphic of sin' and 'graphic of cos' respectively: 5) Add a text 'Esin(2x)' in (pi/2,0] of the first graphic, add a text 'fcos(2x)' in (pi/4,0] of the second graphic graphic of sin graphic of sin 0.5 y1=sin(2x) Ordinate 0 sin(2x) -0.5 0 2. 5 6 3 4 Abscissa graphic of cos 0.5 -6-- e -y2=cos(2x) Ordinate 0 cos(2x) -0-0- -0.5 ope -1 0 0.5 2 1.5 Abscissa 2 2.5 3
