The Math.cosh()
function returns the hyperbolic cosine of a number, that can be expressed using the constant e:
The Math.cosh()
function returns the hyperbolic cosine of a number, that can be expressed using the constant e:
Math.cosh(x)
x
A number.
The hyperbolic cosine of the given number.
Because cosh()
is a static method of Math
, you always use it as Math.cosh()
, rather than as a method of a Math
object you created (Math
is not a constructor).
Math.cosh(0); // 1 Math.cosh(1); // 1.5430806348152437 Math.cosh(-1); // 1.5430806348152437
This can be emulated with the help of the Math.exp()
function:
Math.cosh = Math.cosh || function(x) { return (Math.exp(x) + Math.exp(-x)) / 2; }
or using only one call to the Math.exp()
function:
Math.cosh = Math.cosh || function(x) { var y = Math.exp(x); return (y + 1 / y) / 2; };
