Sinusoid

Sinusoids are mathematical concepts that can be used to describe waves, find angles and lengths and can even be shown on as a function on a graph.

Sinusoidal Wave
Sinusoidal waves are used to describe some forms of wave movement. When plotted on graphs, the sinusoids can be used to calculate the displacement, amplitude, wave number, angular velocity, time period and phase using this equation:

y(x,t) = ymsin(kx + 𝑤t + ɸ)
