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

ParameterRequiredDescription
xYesA 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)
Run

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)
Run

Output

tan(x) : 1.7320508075688767
