Math.asin(-1) Equals -PI/2

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

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

Math.asin(x)

Math.asin(-1) returns -Math.PI / 2 (approximately -1.5708 radians).

Challenge: Verify that Math.asin(-1) equals -Ο€/2.

πŸ’‘ Hints (2)
  • β€’ sin(-Ο€/2) = -1, so asin(-1) = -Ο€/2
  • β€’ asin is an odd function: asin(-x) = -asin(x)
