WebSinusoidal graph. The 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 … WebThe heart of the wave equations as David described them are trigonometry functions, sine and cosine. Trig functions take angles as arguments. The most natural units to express angles in are radians. The circumference of a circle = π times its diameter. The diameter is 2 times the radius, so C = 2πR. Now when the radius equals 1, C = 2π.
