Python | function math.tan ()

In Python, a math module contains a number of math operations that can be easily accomplished using the module. math.tan() returns the tangent of the value passed as an argument. The value passed to this function must be in radians.

Syntax: math.tan (x)

Parameter:
x: value to be passed to tan ()

Returns: Returns the tangent of value passed as argument

Code # 1:

# Python code for tan () demonstration

 
# import & quot; math & quot; for math operations

import math 

 

a = math.pi / 6

 
# returning the tangent of pi / 6

print ( "The value of tangent of pi / 6 is:" , end = "") 

print (math.tan (a))
