About Sine (sin)
In trigonometry, the sine of an angle is the ratio of the length of the opposite side to the length of the hypotenuse in a right-angled triangle.
Formula
sin(θ) = Opposite / Hypotenuse
Properties
The sine function is periodic with a period of 2π (360°). Its value oscillates between -1 and 1.
Common Values
- sin(0°) = 0
- sin(30°) = 0.5
- sin(45°) ≈ 0.7071
- sin(60°) ≈ 0.8660
- sin(90°) = 1
Applications
- Analyzing waveforms in physics and acoustics
