Math.sin() — sin(π) ≈ 0

📖 Usage Example

// Sine of an angle in radians
Math.sin(0)            // → 0
Math.sin(Math.PI / 2)  // → 1

Use Math.sin() to compute the sine of an angle in radians for trigonometry and wave simulations.

Math.sin()

Returns the sine of a number (in radians).

Challenge: Observe that Math.sin(Math.PI) returns a value very close to 0 (floating-point approximation).
