MATLAB Problem:

Plot cos^3(x)/e^x for x values ranging from 0 to 2 (in separate Figure Windows):

- using 20 points in this range

- using 1000 points in this range.

For the first plot use blue x plot markers with solid green lines, and for the second plot use red o plot markers and black dashed lines.

Heres what I have so far but I keep getting an error for figure(2), Matlab comes out with error "vectors must be the same length":

x1 = linspace(0, 2*pi, 20); x2 = linspace(0, 2*pi, 1000); y = (cos(x1).^3)./(exp(x1)); figure(1); plot(x1, y, 'bx', x1, y, '-g') figure(2); plot(x2, y, 'ro', x2, y, '--k')
