Applying mathematical equations to JAVA code

[joshmo]

hello. I would like to know how I can make out a Java code from a given mathematical equation like differentiation equations, summation and integration

[bluerose]

You need to understand the logic of those equation first and use the javadocs (api) to help you with the functions available to solve mathematical problems.

Ofcourse I can get to understand the logic..What I want to know is how i can get, say a given equation to integrate or differentiate a number, then change that logic, to JAVA code..is there any application or tool that can do this?

Probably, do a google search for them. If you're talking about simple differentiation and integration (i.e. power rule) then it is trivial anyway, and so is chain rule for differentiation. Why don't you mention the specific formula you're trying to code and then show some progress or ideas etc on it.

Depends on the equation. A lot of equations are done for you and are included in Math .

double theta = 0.5;
double cosinetheta = Math.cos (theta);

Some equations you'll have to write out or combine with Math functions.

double x = 0.5;
double y = Math.cos (x) + Math.pow (theta, 1.5) - 2 * x + 6.3;

[edit]
And Math is just one of many classes you can use. There is all sorts of stuff out there, both from Sun and from individuals who have posted work.

It all depends, if you want a numerical analysis approach it is a piece of piss. i.e using the trapezium rule for integration.

Something more than that, such as mathematica's engine would be a lot more involved.

You may use mathematics open source API for your purpose. Mathemaca, /Link is a toolkit that integrates Mathematica and Java. http://reference.wolfram.com/mathematica/JLink/ref/java/overview-summary.html
