Sine, Cosine, Tangent functions map angles to ratios of sides in a right triangle or coordinates on the unit circle.
- sin(x): y-coordinate on unit circle
- cos(x): x-coordinate on unit circle
- tan(x): sin(x)/cos(x), vertical slope
Parameters:
- Amplitude: Peak height
- Frequency: How many cycles in 2Ï€
- Phase Shift: Horizontal move left/right
