Suppose that MATLAB is used to plot a sinusoidal signal. The following MATLAB code generates the signal and makes the plot. Derive a formula for the signal; then draw a sketch of the plot that will be done by MATLAB.

dt = 1/100;

tt = -1 : dt : 1;

Fo = 2;

zz = 300*exp(j*(2*pi*Fo*(tt - 0.75)));

xx = real( zz );

plot( tt, xx ), grid on
