Math.acosh(1) Equals Zero

πŸ“– Usage Example
// Inverse hyperbolic cosine (input must be β‰₯ 1)
Math.acosh(1)   // β†’ 0
Math.acosh(2)   // β†’ 1.3169...

Use Math.acosh() to compute the inverse hyperbolic cosine of a number β‰₯ 1.

Math.acosh(x)

Returns the hyperbolic arccosine of a number. Math.acosh(1) returns 0.

Challenge: Use Math.acosh() and verify its result for input 1.

πŸ’‘ Hints (2)
  • β€’ cosh(0) = 1, so acosh(1) = 0
  • β€’ The domain of acosh is [1, ∞)
