Function

Cosh(angle) angle

---

Use

The Cosh() function returns the hyperbolic cosine of an angle. The input must have an angular unit, but unitless is acceptable and will be treated as radians.

Cosh() also works with complex numbers.

Examples of hyperbolic trig functions

• Sinh(pi/4)  = 0.869
• Sinh(1 rad)  = 1.175
• Cosh(30 deg)  = 1.140
• Tanh((30 + 45i) deg)  = 0.781 + 0.625i
