In this tutorial, you will learn about the cos function in python.This will give you the cosine of the angle in degrees. Remember, math.cos() takes the angle in radians, so you may need to convert it if your angle is given in degrees.
cos() in python
The cos() function in Python calculates the cosine of a given angle. The angle must be in radians, not degrees. The result will be a number between -1 and 1, where -1 corresponds to an angle of π radians (180 degrees) and 1 corresponds to an angle of 0 radians (0 degrees).
import math
angle_radians = math.pi / 6
cosine_value = math.cos(angle_radians)
print("Cosine of", angle_radians, "radians is:", cosine_value)
output:
Cosine of 0.5235987755982988 radians is: 0.8660254037844387
