Step 1.9 Using the MatLab code in step 1.8, modify the following: (1) s(t) = s=A1*sin((2*pi*f1*t)+sphase) = 5sin(2150t + /2) (2)

b(t) = b=A2*cos((2*pi*f2*t)+bphase) = 5cos(2150t + 0)

Question 1. Select the best answer regarding your observation from step 1.9.

a. both s and b appear as identical sine waves

b. both s and b appear as identical cosine waves

c. both s and b appear as cosine waves; however, their amplitudes differ

d. s appears as a sine wave while b appears as a cosine wave; both have different amplitudes.

Using MatLab can anyone help me with this question? (the second graph is after the changes being made)
