## degrees() and radians() in Python

degress() and radians() are methods specified in math module in Python 3 and Python 2.

Often one is in need to handle mathematical computation of conversion of radians to degrees and vice-versa, especially in the field of geometry. Python offers inbuilt methods to handle this functionality. Both the functions are discussed in this article.

**radians()**

This function accepts the “**degrees**” as input and converts it into its radians equivalent.

Syntax :

radians(deg)

Parameters :

deg :The degrees value that one needs to convert into radians

Returns :This function returns the floating point radians equivalent of argument.

Computational Equivalent :1 Radians = 180/pi Degrees.

**Code #1 :** Demonstrating radians()

`# Python code to demonstrate` `# working of radians()` ` ` `# for radians` `import` `math` ` ` `# Printing radians equivalents.` `print` `(` `"180 / pi Degrees is equal to Radians : "` `, end ` `=` `"")` `print` `(math.radians(` `180` `/` `math.pi))` ` ` `print` `(` `"180 Degrees is equal to Radians : "` `, end ` `=` `"")` `print` `(math.radians(` `180` `))` ` ` `print` `(` `"1 Degrees is equal to Radians : "` `, end ` `=` `"")` `print` `(math.radians(` `1` `))` |

Output:

180/pi Degrees is equal to Radians : 1.0 180 Degrees is equal to Radians : 3.141592653589793 1 Degrees is equal to Radians : 0.017453292519943295

**degrees()**

This function accepts the “**radians**” as input and converts it into its degrees equivalent.

Syntax :

degrees(rad)

Parameters :

rad :The radians value that one needs to convert into degrees.

Returns :This function returns the floating point degrees equivalent of argument.

Computational Equivalent :1 Degrees = pi/180 Radians.

**Code #2 :** Demonstrating degrees()

`# Python code to demonstrate` `# working of degrees()` ` ` `# for degrees()` `import` `math` ` ` `# Printing degrees equivalents.` `print` `(` `"pi / 180 Radians is equal to Degrees : "` `, end ` `=` `"")` `print` `(math.degrees(math.pi ` `/` `180` `))` ` ` `print` `(` `"180 Radians is equal to Degrees : "` `, end ` `=` `"")` `print` `(math.degrees(` `180` `))` ` ` `print` `(` `"1 Radians is equal to Degrees : "` `, end ` `=` `"")` `print` `(math.degrees(` `1` `))` |

Output:

pi/180 Radians is equal to Degrees : 1.0 180 Radians is equal to Degrees : 10313.240312354817 1 Radians is equal to Degrees : 57.29577951308232

**Application :**

There are many possible applications of these functions in mathematical computations related to geometry and has a certain applications in astronomical computations as well.
