1. (10) Write the MATLAB statements required to plot sin x versus cos 2x from 0 to 2x in steps of /10. The points should be connected by a red line and each point should be marked with a blue circular marker. 2. Write the MATLAB text string that will produce the following expressions: a. (5) b. (5) f(x)=sin 0 cos 20 Plot of Ex versus x 3. (5) How do you display the backslash (1) character in a text string? 4. (10) Euler's Equation defines a complex exponential number e as follows: elx = cos(x) + jsin(x) a. Create a 2D plot of this function as x varies from - to + . Be sure to include appropriate axes labels and a descriptive title.
