Python Number tan() Function
Description:
This function returns the tangent of x radians.
Syntax:
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:
Here is the detail of parameters:
Return Value:
The tan() function returns a numeric value between -1 and 1, which represents the tangent of the parameter x.
Example:
#!/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)
|
This will produce 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
