As more and more industries turn to Python for their programming needs, it is important to be familiar with the different functions and capabilities of this versatile programming language. One frequently encountered task is converting radians to degrees, which is often used in various fields, such as science, engineering, and mathematics. In this article, we will provide a comprehensive guide on how to convert radians to degrees in Python, including the use of the math and numpy libraries, custom functions, and best practices for working with angles.

Using the math library for conversion

One of the most common ways to convert radians to degrees in python is by using the math library. The math library provides several built-in functions that can be used for mathematical operations, including converting radians to degrees and vice versa.

The radians() function for converting degrees to radians

To convert degrees to radians , we can use the radians() function from the math library. This function takes a single parameter, which is the angle in degrees, and returns the corresponding angle in radians.

import mathangle_degrees = 45 angle_radians = math.radians(angle_degrees)print(angle_radians) 

In this example, we first import the math library and then set the value of angle_degrees to 45. We then use the radians() function to convert the angle to radians and store the result in the angle_radians variable. Finally, we print the value of angle_radians .

The degrees() function for converting radians to degrees

To convert radians to degrees, we can use the degrees() function from the math library. This function takes a single parameter, which is the angle in radians, and returns the corresponding angle in degrees.

import mathangle_radians = 0.7853981633974483 angle_degrees = math.degrees(angle_radians)print(angle_degrees) 

In this example, we first import the math library and then set the value of angle_radians to 0.7853981633974483. We then use the degrees() function to convert the angle to degrees and store the result in the angle_degrees variable. Finally, we print the value of angle_degrees .

Other useful functions in the math library

The math library provides several other useful functions for trigonometric calculations, including sin() , cos() , and tan() . These functions take an angle in radians as a parameter and return the corresponding trigonometric value. For example, to calculate the sine of an angle in radians, we can use the sin() function:

import mathangle_radians = 0.7853981633974483 sin_value = math.sin(angle_radians)print(sin_value) 

In addition, the math library also provides the atan2() function for finding the angle between two points. This function takes two parameters, which are the y and x coordinates of the two points, and returns the corresponding angle in radians.

Using the numpy library for conversion

Another way to convert radians to degrees in Python is by using the numpy library. The numpy library provides several functions for working with arrays, including converting between degrees and radians.

The rad2deg() function for converting radians to degrees

To convert radians to degrees using numpy, we can use the rad2deg() function. This function takes a single parameter, which is the angle in radians, and returns the corresponding angle in degrees.

import numpy as npangle_radians = np.pi/4 angle_degrees = np.rad2deg(angle_radians)print(angle_degrees) 

In this example, we first import the numpy library and then set the value of angle_radians to np.pi/4 , which is equivalent to 45 degrees. We then use the rad2deg() function to convert the angle to degrees and store the result in the angle_degrees variable. Finally, we print the value of angle_degrees .

The deg2rad() function for converting degrees to radians

To convert degrees to radians using numpy, we can use the deg2rad() function. This function takes a single parameter, which is the angle in degrees, and returns the corresponding angle in radians.

import numpy as npangle_degrees = 45 angle_radians = np.deg2rad(angle_degrees)print(angle_radians) 

In this example, we first import the numpy library and then set the value of angle_degrees to 45. We then use the deg2rad() function to convert the angle to radians and store the result in the angle_radians variable. Finally, we print the value of angle_radians .

Other useful functions in the numpy library

The numpy library provides several other useful functions for working with arrays of angles, including the arange() function. This function can be used to create arrays of angles with a specified range and step size.

import numpy as npangles_degrees = np.arange(0, 360, 45) angles_radians = np.deg2rad(angles_degrees)print(angles_degrees) print(angles_radians) 

[ 0 45 90 135 180 225 270 315] [0. 0.78539816 1.57079633 2.35619449 3.14159265 3.92699082 4.71238898 5.49778714] 

In this example, we first import the numpy library and then use the arange() function to create an array of angles in degrees with a range of 0 to 360 and a step size of 45. We then use the deg2rad() function to convert the array of angles to radians and store the result in the angles_radians variable. Finally, we print both the array of angles in degrees and radians.

Custom functions for conversion

In addition to using the built-in functions provided by the math and numpy libraries, we can also create our own custom functions for converting between radians and degrees. This can be useful if we need to perform other operations or calculations in addition to the conversion.

Example of a custom function for converting radians to degrees

import mathdef radians_to_degrees(angle_radians): angle_degrees = angle_radians * 180 / math.pi return angle_degreesangle_radians = 0.7853981633974483 angle_degrees = radians_to_degrees(angle_radians)print(angle_degrees) 

In this example, we define a custom function called radians_to_degrees() that takes a single parameter, which is the angle in radians, and returns the corresponding angle in degrees. We then use this function to convert the angle 0.7853981633974483 to degrees and store the result in the angle_degrees variable. Finally, we print the value of angle_degrees .

Example of a custom function for converting degrees to radians

import mathdef degrees_to_radians(angle_degrees): angle_radians = angle_degrees * math.pi / 180 return angle_radiansangle_degrees = 45 angle_radians = degrees_to_radians(angle_degrees)print(angle_radians) 

In this example, we define a custom function called degrees_to_radians() that takes a single parameter, which is the angle in degrees, and returns the corresponding angle in radians. We then use this function to convert the angle 45 to radians and store the result in the angle_radians variable. Finally, we print the value of angle_radians .

Перевод градусов в радианы и наоборот в Python

degrees() и radians () в Python — это методы, указанные в математическом модуле в Python 3 и Python 2. Часто требуется выполнить математические вычисления перевода радианов в градусы в Python и наоборот, особенно в области геометрии.

Что такое функция radians() в Python?

Python radians() — это встроенный метод, определенный в математическом модуле, который используется для преобразования угла x (который является параметром) из градусов в радианы. Например, если x передается в качестве параметра в градусах, то функция(радианы(x)) возвращает значение этого угла в радианах.

Мы будем использовать математический модуль, импортировав его. После импорта модуля мы можем вызвать функцию radians(), используя статический объект.

Синтаксис

Здесь var — это переменная, которую мы должны преобразовать из градусов в радианы.

Параметры

Метод принимает один аргумент var, который принимает значения числового типа данных и выдает TypeError, если передается параметр любого другого типа данных.

Возвращаемое значение

radians() возвращает значение числа в радианах в типе данных float.

Примеры программ с использованием метода radians() в Python

Пример 1

Напишите программу, демонстрирующую работу метода radians() в Python.

В приведенном выше примере мы видели, что, минуя допустимый параметр в функции градусов, мы получаем значение угла в радианах. Здесь мы прошли разные углы и получили разные значения.

Пример 2

Напишите программу для передачи значения вне допустимого диапазона из функции radians() и отображения вывода.

В этом примере мы видели, что передача параметра, который не является реальным числом, вызывает ошибку TypeError.

Python radians() со списком и кортежем

В первых трех операторах мы использовали функцию radians () с нулями, положительными целыми и отрицательными целыми значениями в качестве аргументов. В следующих двух утверждениях мы использовали функцию с положительными и отрицательными десятичными значениями в качестве параметров.

В следующих двух утверждениях мы использовали метод radians () для элементов Python Tuple и Python List. Если вы наблюдаете приведенный выше вывод, функция radians() работает с ними правильно.

Мы попробовали метод radians() непосредственно для нескольких значений. Затем мы использовали функцию radians() для значений круговой диаграммы.

В последнем коде мы использовали функцию radians() для значения String. Как мы уже говорили, оно возвращает TypeError в качестве вывода.

Функция degrees() в Python

Python Degrees() — это встроенный метод, определенный в математическом модуле, который используется для преобразования угла x (который является параметром) из радианов в градусы. Например, если x передается в качестве параметра в функцию градусов (degrees(x)), она возвращает значение угла в градусах. Функция Python math.degrees() существует в стандартной математической библиотеке.
