Math.atan(1) Equals PI/4

πŸ“– Usage Example
// Inverse tangent β€” result in radians
Math.atan(1)   // β†’ 0.7853... (Ο€/4)
Math.atan(0)   // β†’ 0

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

Math.atan(x)

Math.atan(1) returns Math.PI / 4 (approximately 0.7854 radians or 45Β°).

Challenge: Verify that Math.atan(1) equals Ο€/4.

πŸ’‘ Hints (2)
  • β€’ tan(45Β°) = 1, so atan(1) = Ο€/4 β‰ˆ 0.7854
  • β€’ Math.PI / 4 β‰ˆ 0.7854
