StrictMath cos() Method in Java with Examples
All methods of java.lang.StrictMath class : Set 1, Set 2
The java.lang.StrictMath.cos() is an inbuilt method in Java which is used to return the cosine value of a given angle. The method returns NaN when the given argument is NaN or infinity.
Syntax:
public static double cos(double num)
Parameters: The method accepts one parameter num of double type and refers to the angle in radian whose cosine value is to be returned.
Return Value: The method returns the cosine of the argument.
Examples :
Input: num = 62.0
Output: 0.6735071623235862
Input: num = 64.6
Output: -0.19607204956188945
Below programs illustrate the java.lang.StrictMath.cos() method:
Program 1:
java
import java.lang.*;
public class Geeks {
public static void main(String[] args) {
double num1 = 0.0 , num2= 1.0 , num3= 64.6 ;
double cosValue = StrictMath.cos(num1);
System.out.println("The cosine of "+
num1+" = " + cosValue);
cosValue = StrictMath.cos(num2);
System.out.println("The cosine of "+
num2+" = " + cosValue);
cosValue = StrictMath.cos(num3);
System.out.println("The cosine of "+
num3+" = " + cosValue);}
}
|
Output:
The cosine of 0.0 = 1.0
The cosine of 1.0 = 0.5403023058681398
The cosine of 64.6 = -0.19607204956188945
Program 2:
java
import java.lang.*;
public class Geeks {
public static void main(String[] args) {
double num1= - 62.0 , num2 = 1.0 ;
double num3= ( 45 *(Math.PI))/ 180 ;
double cosValue = StrictMath.cos(num1);
System.out.println("The cosine of "+
num1+" = " + cosValue);
cosValue = StrictMath.cos(num2);
System.out.println("The cosine of "+
num2+" = " + cosValue);
cosValue = StrictMath.cos(num3);
System.out.println("The cosine of "+
num3+" = " + cosValue);}
}
|
Output:
The cosine of -62.0 = 0.6735071623235862
The cosine of 1.0 = 0.5403023058681398
The cosine of 0.7853981633974483 = 0.7071067811865476
