Definition
In a right triangle, sin(angle) = opposite / hypotenuse.
On the unit circle, sin(angle) is the y-coordinate of the point at that angle.
Key Values
Esempio Risolto
Calculate sin(30°).
- 0130° in radians = 30 × pi/180 = pi/6 ≈ 0.5236
- 02sin(30°) = 0.5
- 03cos(30°) = √3/2 ≈ 0.8660
- 04tan(30°) = 1/√3 ≈ 0.5774
Domande Frequenti
What is the sine function?
Sine is a trigonometric function that gives the ratio of the opposite side to the hypotenuse in a right triangle, or the y-coordinate on the unit circle.
What is the range of sine?
The sine function outputs values between -1 and 1. sin(90°) = 1 and sin(270°) = -1.
What is the period of sine?
Sine has a period of 360° (2pi radians). The function repeats every full rotation.
