Find the period, To, and fundamental frequency, fo of the signals listed below.
B. x(t) = 56 + 42 sin(2 pi 100 t)
C. x(t) = 56 + 42 sin(2 pi 100 t) + 56 cos(2 pi 202 t)
D. x(t)=56 + 42 sin(2 pi 123.45 t) - 700 sin(2 pi 34.308 t + 98 )
E. x(t)=56-73 cos(2 pi 456.322 t-8)+78 sin(2 pi 876.4 t + pi) - 98 sin(2 pi 1000 t)
F. x(t)=t² + cos(2 pi 100 t)
