How to integrate any expression using java?

Question

Should it be import some mathematical tools, or we can integrate directly using logics only

Answer 1

Hy Sonu Kumar
By integrate any expression , U mean integration of any expression in java ?
● For integration of Polynomial terms , it will be easy (no need of importing any extra libraries , can be solve through logic only)
● if U want to integrate ANY expression , then it will be a tough to do(involvement of trignometric & logaritmic forms also) [try this link : https://www.quora.com/What-is-the-algorithm-to-integrate-a-function-using-a-computer-program , still only elementary functions , Composite function are might not taken]

//M.S.D answer was to find Real roots of quadratic equation

//U should go for integration of Polynomial expressions only according to me

Answer 2

Sonu Kumar
● By finding discriminant value -ve , U can make use of iota(i) for representation of imaginary part of roots.
● I made little change in formula for representation :
[-b +- -i(-(b^2-4ac))^(1/2)]/(2a)
● -D taken in place of D as value of D will be -ve & sqrt() function don't work for -ve values.

Answer 3

Mohit the coder, If roots are not real then??

Answer 4

Yah

Answer 5

Can i solve using java or not?

Answer 6

Ok how can i solve it ?

Answer 7

Ok sir ... thanks alot

Answer 8

You can solve quardatic equation like this
class QuadraticEquation
{

public static void main(String[] args)
{
/*
* Suppose our Quadratic Equation to be solved is 2x2 + 6x + 4 = 0 .
* (Assuming that both roots are real valued)
*
* General form of a Quadratic Equation is ax2 + bx + c = 0 where 'a' is
* not equal to 0
*
* Hence a = 2, b = 6 and c = 4.
*/

int a = 2;
int b = 6;
int c = 4;

// Finding out the roots
double temp1 = Math.sqrt(b * b - 4 * a * c);

double root1 = (-b + temp1) / (2 * a);
double root2 = (-b - temp1) / (2 * a);

System.out
.println("The roots of the Quadratic Equation \"2x2 + 6x + 4 = 0\" are "
+ root1 + " and " + root2);

}
}

Answer 9

Yes if you want to use polynomial evalution of expressions then you can do that by regression formulas and polynomial regression evaluator which will evaluate polynomial equation

Answer 10

You can use neumerical integration by simpaon's, rectungular and trapezium, Gauss legendre ect formula to solve the integration

Answer 11

Do you mean any quardatic equation, you can use your logic to perform mathematical operation

Answer 12

Yes you can solve that easily and if you want to import some mathematical libraries then you can include that
java.lang.Math.sqrt(x);
import java.lang.Math; Math.sqrt(x);
