WebThe term sinusoid is based on the sine function y = sin(x), shown below. Graphs that have a form similar to the sine graph are referred to as sinusoidal graphs. Notice the periodic nature of the sine graph. It repeats every 2π and has smooth curves. Below are some of the properties of the sine function: WebA periodic sinusoidal voltage is constant and can be defined as V(t) = Vmax*cos (ωt) with a period of T. Then we can calculate the root-mean-square (rms) value of a sinusoidal voltage (V (t)) as: Integrating through with limits taken from 0 to 360 o or “T”, the period gives: Where: Vm is the peak or maximum value of the waveform.
