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.

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.
