Starting with the plot in Fig. 1, sketch a plot of x (t − t1) when t1 = 0.0075. Repeat for t1 = −0.01. Make sure that you shift in the correct direction. For each case, compute the phase of the resulting time-shifted sinusoid.

Sinusoidal signal with parameters A = 20, ω0 = 2π (40), f0 = 40 Hz, and φ = 0.4π rad.
