Answer 1

Answer:

By Java Program

Explanation:

Below example shows how to calculate natural logarithm value of a given number using Math.log() function.

Code:

package com.java2novice.math;

public class MyLogEx {

public static void main(String a[]){

System.out.println("Natural logarithm value of 2 is: "+Math.log(2));

System.out.println("Natural logarithm value of 10 is: "+Math.log(10));

System.out.println("Natural logarithm value of 15 is: "+Math.log(15));

}

}

Output:

Natural logarithm value of 2 is: 0.6931471805599453

Natural logarithm value of 10 is: 2.302585092994046

Natural logarithm value of 15 is: 2.70805020110221
