Math.cosh(0) Equals 1

πŸ“– Usage Example
// Hyperbolic cosine
Math.cosh(0)   // β†’ 1
Math.cosh(1)   // β†’ 1.5430...

Use Math.cosh() to compute the hyperbolic cosine, commonly used in physics and engineering formulas.

Math.cosh(x)

Returns the hyperbolic cosine of a number. Math.cosh(0) returns 1.

Challenge: Use Math.cosh() and verify its result for input 0.

πŸ’‘ Hints (2)
  • β€’ cosh(x) = (eΛ£ + e⁻ˣ) / 2, and cosh(0) = (1 + 1) / 2 = 1
  • β€’ The minimum value of cosh is 1, achieved at x = 0
