Math.acos(0) Equals PI/2

πŸ“– Usage Example
// Inverse cosine β€” result in radians
Math.acos(1)   // β†’ 0
Math.acos(0)   // β†’ 1.5707... (Ο€/2)

Use Math.acos() to find the angle (in radians) whose cosine equals a given value.

Math.acos(x)

Math.acos(0) returns Math.PI / 2 (approximately 1.5708 radians).

Challenge: Verify that Math.acos(0) equals Ο€/2.
