Part 5: Resolution of time (15 points) Write MATLAB Code to solve each of the following and answer each question using comment after %. (15 points, 3 points each) 1. Create a time series for 1 cycle of a 400 Hz cosine function where the increment is 0.001 2. Plot the signal in blue (remember to keep the 'hold on') 3. Now decrease the increment to 0.0005 and plot the signal in red 4. Now decrease the increment to 0.00005 and plot the signal in green 5. Discuss what happens to your signal and why
