What is math.tanh() in Python?
The tanh() function in Python returns a number’s hyperbolic tangent. To be more specific, it returns the hyperbolic tangent of a number in radians.
Figure 1 shows the mathematical representation of the tanh() function.
Note: The
mathmodule is required for this function.
Syntax
tanh(num)
Parameter
This function requires a number that represents an angle in radians as a parameter.
To convert degrees to radians, use:
radians = degrees * ( PI / 180.0 )
Return value
tanh() returns the hyperbolic tangent of a number (radians) that is set as a parameter.
Example
import math#positive number in radiansprint "The value of tanh(2.3) : ", math.tanh(2.3)#negative number in radiansprint "The value of tanh(-2.3) : ", math.tanh(-2.3)#converting the degrees angle into radians and then applying tanh()#degrees = 45#PI = 3.14159265result = 45.0 * (math.pi / 180.0)print "The value of tanh("+str(result)+") : ", math.tanh(result)
