conversion of angles and radians

The Math.toradians () method is used to convert an angle to radians (static method)

public static double Toradians (double angdeg)

Angdeg: angle-represented angle

Return value: The value of the angle angdeg in radians

Math. The Todegrees () method is used to convert radians to angles (static methods)
public static double todegress (double Angrad)

Angrad: The angle expressed in radians
return value: Angular Angrad value represented by angle

 Packagecynical_gary; Public classCynical_text { Public Static voidMain (string[] args) {System.out.println ("30° corresponds to the sine value:" +math.sin (MATH.PI/6));//calculates the sine value of 30°System.out.println ("30° corresponds to the cosine value is:" +math.cos (MATH.PI/6));//calculates the cosine of 30°System.out.println ("30° corresponds to the tangent value is:" +math.tan (MATH.PI/6));//calculate the tangent of 30°    }}/*The sine value corresponding to the output 30° is: 0.4999999999999999430° corresponds to the cosine value is: 0.866025403784438730° corresponding tangent value is: 0.5773502691896257*/
