This function returns the cosine of x radians.
cos(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 cos() function returns a numeric value between -1 and 1, which represents the cosine of the angle.
#!/usr/bin/python import math print "cos(3) : ", math.cos(3) print "cos(-3) : ", math.cos(-3) print "cos(0) : ", math.cos(0) print "cos(math.pi) : ", math.cos(math.pi) print "cos(2*math.pi) : ", math.cos(2*math.pi) |
This will produce following result:
cos(3) : -0.9899924966 cos(-3) : -0.9899924966 cos(0) : 1.0 cos(math.pi) : -1.0 cos(2*math.pi) : 1.0 |
