Python Number tan() Method
Description
Python number method tan() returns the tangent of x radians.
Syntax
Following is the syntax for tan() method −
tan(x)
Note − This function is not accessible directly, so we need to import math module and then we need to call this function using math static object.
Parameters
x − This must be a numeric value.
Return Value
This method returns a numeric value between -1 and 1, which represents the tangent of the parameter x.
Example
The following example shows the usage of tan() method.
#!/usr/bin/python import math print "tan(3) : ", math.tan(3) print "tan(-3) : ", math.tan(-3) print "tan(0) : ", math.tan(0) print "tan(math.pi) : ", math.tan(math.pi) print "tan(math.pi/2) : ", math.tan(math.pi/2) print "tan(math.pi/4) : ", math.tan(math.pi/4)
When we run above program, it produces following result −
tan(3) : -0.142546543074 tan(-3) : 0.142546543074 tan(0) : 0.0 tan(math.pi) : -1.22460635382e-16 tan(math.pi/2) : 1.63317787284e+16 tan(math.pi/4) : 1.0
