The period of a sinusoidal source is the time required for the sinusoid to pass through all of its possible values. we use the symbol t to represent the period of a sinusoid. the period and the frequency are inversely related. a sinusoidal source described by the function cos(ωt) has a frequency of ω radians/second, or a frequency f=ω/2π hz. the units hertz represents the number of cycles per second. since the period is the number of seconds per cycle, the period is the inverse of the frequency in hertz: t=1f substituting the frequency in radians/second, ω, for the frequency in hz gives us another way to calculate the period: t=2πω what is the period of the voltage source described as v(t)=50cos(2000t−45∘) mv? express your answer to two digits after the decimal point and include the appropriate units.
