Math.tan() — tan(π) ≈ 0

📖 Usage Example

// Tangent of an angle in radians
Math.tan(0)            // → 0
Math.tan(Math.PI / 4)  // → 1

Use Math.tan() to compute the tangent of an angle in radians for trigonometry and slope calculations.

Math.tan()

Returns the tangent of a number (in radians).

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

💡 Hints (1)

• tan(π) = 0 mathematically; floating-point gives a tiny near-zero value due to π approximation
