This function returns the tangent of x radians.
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.
Here is the detail of parameters:
x: Must be a numeric value
The tan() function returns a numeric value between -1 and 1, which represents the tangent of the parameter x.
#!/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 |
