What is the sine function that describes the waveform?
A sine wave is a geometric waveform that oscillates (moves up, down, or side-to-side) periodically, and is defined by the function y = sin x. In other words, it is an s-shaped, smooth wave that oscillates above and below zero.
How do you describe a sinusoidal function?
A sinusoidal function is a function that is based on the sine function, which is a periodic function that smoothly oscillates between high and low values. Sinusoidal functions can also be based on the cosine function since it is just a horizontal shift of the sine function.
How do you describe a sine graph?
The graph of y=sin(x) is like a wave that forever oscillates between -1 and 1, in a shape that repeats itself every 2π units.
What are two main features used to help describe a sine wave?
Since we are going to ignore phase for right now, we really only need two terms to completely describe a sine wave: its amplitude and its frequency.
