Radians
Radian Measure
An angle measurement where one radian equals the angle subtended by an arc equal in length to the radius.
Détail technique
Radians functions relate angles to side ratios in right triangles. In computing, angles are typically in radians (π radians = 180°). Key identities: sin²θ + cos²θ = 1, sin(2θ) = 2sinθcosθ. Applications include wave generation (audio synthesis), rotation transforms (2D/3D graphics), signal processing (Fourier analysis), and geolocation (haversine formula for great-circle distance). JavaScript's Math.sin() expects radians, so convert degrees with: radians = degrees × π / 180.
Exemple
``` Trigonometric functions (right triangle): sin(θ) = opposite / hypotenuse cos(θ) = adjacent / hypotenuse tan(θ) = opposite / adjacent For a 30° angle: sin(30°) = 0.5, cos(30°) ≈ 0.866, tan(30°) ≈ 0.577 Radians: 180° = π rad → degrees × π / 180 = radians ```
