Lissajous figures are used in the study of electrical circuits to determine the phase difference
between a known voltage
and an unknown voltage
having the same frequency. The voltages are graphed parametrically as
and
. If
is acute, then
where y int is the nonnegative y -intercept and y max is the maximum y -value on the curve. Graph the parametric curve and use the graph to approximate
in degrees if
