Python math.tan() - Tangent Function
Python math.tan()
math.tan(x) function returns the tangent of x radians.
The return value lies in [-inf, inf].
Syntax
The syntax to call tan() function is
math.tan(x)
where
Parameter | Required | Description |
---|---|---|
x | Yes | A numeric value that represents angle in radians. |
Examples
In the following example, we find the tangent of 0.5 radians using tan() function of math module.
Python Program
import math
x = 0.5 #radians
result = math.tan(x)
print('tan(x) :', result)
Output
tan(x) : 0.5463024898437905
We can take angle in degrees and convert the degrees into radians using math.radians() function, and then find the tangent of this angle.
In the following program, we find the tangent of 60 degrees.
Python Program
import math
x = 60 #degrees
x = math.radians(x) #radians
result = math.tan(x)
print('tan(x) :', result)
Output
tan(x) : 1.7320508075688767
