Show the MATLAB code used to plot both functions
a) y = 5 cos (pi*t – pi*x) (V)
f=0.5 Hz, λ=2cm, phase angle = 0
b) y = 5 e^(-αx) cos (2pift-2pix/λ) (V)
f=0,803 Hz, λ=2.874cm, pjase angle = 0
Use the frequency, wavelength and attenuation shown in the figure below when plotting graph b)
Place labels for the x and y axis showing appropriate units.
Extend the x-axis to 10 cm and use a sampling rate of 0.1 mm.
