Python Number cos() Function
Description:
This function returns the cosine 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 cos() function returns a numeric value between -1 and 1, which represents the cosine of the angle.
Example:
#!/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
