Terms: amplitude (A), phase angle (p), frequency (f), angular frequency (w),
period (T), peak value (Vp), peak-to-peak value (Vpp).
Draw a 60 Hz, 5 Vp sine wave on a coordinate axis and graphically identify as
many of the terms as possible from the previous section. Use voltage in volts
for the y-axis, and time in milliseconds for the x-axis. You can use the blank
OSC templates shown in the procedure section to draw the signals.
