C++ Math acosh()
The function computes the arc hyperbolic cosine of an angle given in radian.
Where, an arc hyperbolic cosine is the inverse operation of hyperbolic cosine.
cosh-1x = acosh(x);
Syntax
Suppose an angle is ‘x’:
Parameter
x: The value whose arc hyperbolic cosine is to be computed.
Return value
It returns the arc hyperbolic cosine of x.
Example 1
Let’s see the simple example when the value of degree is integer type.
Output:
Value of degree is : 30 cosh(x) : 1.14009 acosh(x) : -nan
In this example, acosh() function computes the arc hyperbolic cosine of x and returns the value -nan.
Example 2
Let’s see the simple example when the value of degree is float type.
Output:
Value of degree is : 15.7 cosh(x) : 1.03443 acosh(x) : -nan
In this example, acosh() computes the arc hyperbolic cosine of x and returns the value -nan.
