How to find cosine of an angle using Python?
Python comes with an amazing standard math library that provides all trigonometric functions like sin, cos, etc. You can import that library and use these functions. Note that these functions expect angles in radians. For example,
import math angle1 = math.radians(90) angle2 = math.radians(60) print(math.cos(angle1)) print(math.cos(angle2))
This will give the output:
6.123233995736766e-17 0.5
The first value is very close to zero. Such errors come due to computation limits.
