atan2() function in Python
Trigonometry is a field of mathematics that studies the relationship between the angles and side lengths of triangles.
The relationship between angles and sides is calculated with the help of some special operations, such as 正弦,,,, etc.余弦正切余弦
Since it is an essential component in mathematics and many real-world problems can be solved or addressed using them, computer systems have the utility to perform these calculations efficiently and dynamically.
Essentially, it is the programming language that holds these utilities. The above listed are just a few of a huge list of things used in this domain.
Python programming language is a dynamically typed, multi-purpose language that excels in some major computer science fields such as web development, machine learning, data science, artificial intelligence, game development, etc.
The Python programming language has a mathmodule that contains most of the mathematical operations one would need. mathThe module is part of the Python standard library.
三角It also includes methods to
perform operations efficiently . This module contains a method atan2()that calculates y / xthe inverse tangent in radians.
atan2()Using the method
in Python
atan2()Methods are mathpart of Python's module.
This method accepts two floating point values, ythe sum x, representing a ratio y / x, and returns [-π, π]a result in the range , inclusive of the two values.
Here, xand yare the coordinates of the point in the two-dimensional plane (x, y). Since atan2()the method returns the result in radians, it can be converted to degrees with the help of the following equation.
1 radian = 57.296 degrees
1 radian * 180 / π = 57.296 degrees
Let's understand how to use atan2()the method with the help of some relevant examples. See the following Python code.
import math
print(math.atan2(1, 1))
print(math.atan2(-1, 1))
print(math.atan2(-12, 14))
print(math.atan2(111, -11))
print(math.atan2(-34, -421))
Output:
0.7853981633974483
-0.7853981633974483
-0.7086262721276703
1.6695729188625594
-3.0610074523126483
