Python tan() is an inbuilt method defined under the math module, which is used to find the tan value of the parameter passed in radians. For example, if x is passed as a parameter in tan function (tan(x)), it returns the tan value of x in radians. We can use a math module by importing it. The syntax for it would be import math; after importing, we use to call the tan() function using the static object.

#### Syntax

``math.tan(var)``

Here var is the variable of which tan we have to find.
