Examples of use
Basic calculation for an integer
=COSH(0)
Result: 1 (the hyperbolic cosine of zero is one).
Calculation for a fractional number
=COSH(1.5)
Result: 2.35241.
Calculation for a negative number
=COSH(−2)
Result: 3.76220, since the function is even: COSH(-x) = COSH(x).
Notes
The COSH function is defined for all real numbers, and its values are always positive or equal to 1.
