Please paste in both your code and your plots for each part. [For help, watch this video: https://youtu.be/9GhUXhAOja4 ] s_1 (x)= cos(x) s_2 (x)=2cos(2x) s_3 (x)=3cos(3x) Plot all 3 functions in the same plot. Use different colors and different line styles to distinguish the curves. Add a legend. Plot them in three separate plots. All plots should be in the same row. Plot them in three separate plots. All plots should be in the same column.
