Math.sin() — sin(π/2) = 1

📖 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: Verify that Math.sin(Math.PI/2) returns approximately 1.
