C++ Math tanh()
The function computes the hyperbolic tangent of an angle given in radian.
Mathematically,
tanhx = ex -e-x/ ex+e-x
Syntax
Suppose the angle is ‘x’:
Parameter
x: The value whose hyperbolic tangent is to be computed.
Return value
It returns the hyperbolic tangent of x.
Example 1
Let’s see the simple example when the value of x is integer type.
Output:
Value of degree is : 60 tanh(x) : 0.780507
In this example, tanh(x) function computes the hyperbolic tangent of x and returns the value 0.78.
Example 2
Let’s see the simple example when the value of x is float type.
Output:
Value of degree is : 45.2 tanh(x) : 0.657552
In this example, tanh(x) function computes the hyperbolic tangent of x and returns the value 0.65.
