Java Math.toRadians() to change Degree input to Radians

Math.toRadians() returns the value after converting input degree number to radians.
Syntax

Math.toRadians(input_number)

Note that all input numbers are in degree.

Here are some examples.

System.out.println(Math.toRadians(180)); //3.141592653589793
System.out.println(Math.toRadians(90));   //1.5707963267948966
System.out.println(Math.toRadians(0));    //0.0
System.out.println(Math.toRadians(1.22)); //0.02129301687433082
System.out.println(Math.toRadians(-1.22)); //-0.02129301687433082
System.out.println(Math.toRadians(-120)); // -2.0943951023931953

Practical Use of Math.toRadians() in Java

The Math.toRadians() method in Java converts an angle measured in degrees to an equivalent angle in radians, which is often required in trigonometric calculations. Some practical uses include:

Game development: When working with angles for movement, rotations, or animations, radians are required by trigonometric functions like Math.sin() and Math.cos().
Graphics programming: In computer graphics and simulations, angles for transformations (such as rotations of objects) are usually expressed in radians.
Physics simulations: For calculating angular velocity, acceleration, or any rotational motion, physics engines often require angles in radians.
Navigation systems: Applications such as GPS or mapping software that calculate directions or turn angles can use radians for trigonometric calculations.

Using Math.toRadians() ensures that angles are correctly converted for functions that require radians, making it essential for applications involving geometric or rotational computations.
