: Create a Matlab script that generates and plots three trigonometric functions, namely, a sine wave, a cosine wave, and a tangent wave, over a specified range. 1. Define a time vector 't' that spans from 0 to 2*pi (or any desired range). 2. Calculate the corresponding values for sine, cosine, and tangent functions for this 't' vector. 3. Use the subplot command to create a 2x2 grid of subplots. 4. In the first subplot, plot the sine wave. 5. In the second subplot, plot the cosine wave. 6. In the third subplot, plot the tangent wave. 7. Use the hold on command to overlay the plots of these functions in their respective subplots. 8. Label the axes and add a title to each subplot for clarity. 9. Finally, display the entire figure. Part (2) for the figure displayed below plot using subplot the following -2 X(t) x(-t) x(t/2) x(t+1) x(2-2t) 2 1 1 x(t) 3
