Python math.cos() Method
Python math.cos() Method in python is used to returns the cosine of the given number radians and it accepts a number.
Syntax:math.cos(x)
Parameter Values
| Parameter | Description |
|---|---|
| x | It is required a number to find the cosine, and it returns a TypeError |
import math
print (math.cos(0.02))
print (math.cos(-1.67))
print (math.cos(4))
print (math.cos(6.873435))
Output:
0.9998000066665778
-0.09904103659872801
-0.6536436208636119

import math
x = -4
print("cos(",x,") is = ", math.cos(x))
x = 2
print("cos(",x,") is = ", math.cos(x))
x = -1.562
print("cos(",x,") is = ", math.cos(x))
x = -2
print("cos(",x,") is = ", math.cos(x))
Output:
cos( -4 ) is = -0.6536436208636119
cos( 2 ) is = -0.4161468365471424
cos( -1.562 ) is = 0.0087962133588359
cos( -2 ) is = -0.4161468365471424
cos( -4 ) is = -0.6536436208636119
cos( 2 ) is = -0.4161468365471424
cos( -1.562 ) is = 0.0087962133588359
cos( -2 ) is = -0.4161468365471424
