Example

Provide the cosine values for various angles.

System.out.println(Math.cos(3));
System.out.println(Math.cos(-3));
System.out.println(Math.cos(0));
System.out.println(Math.cos(Math.PI));
System.out.println(Math.cos(Math.PI/2));

Definition and Usage

The cos() method computes the cosine of an angle.

Note: Angles are expressed in radians.

Hint: Utilize the constant Math.PI to express angles as fractions of PI.
