kingpuka Posted December 10, 2005 Share Posted December 10, 2005 Hello all, I've been searching for a while and I can't seem to be getting anywhere. Does anyone have any functions to do derivatives and other calculus functions in php? Or, do you know where I can find one? I hope somebody out here has an idea.

Found it from php.net. :) Link to comment https://www.neowin.net/forum/topic/406790-php-calculus-functions/#findComment-586903381 Share on other sites More sharing options...
0 kingpuka Posted December 10, 2005 Author Share Posted December 10, 2005 Hey there, Check this out. Found it from php.net. :) Thanks for what you found, but those are not what I'm looking for. Also, I don't think those are implemented into PHP yet because they don't have any documentation. I could be wrong though.

0 kingpuka Posted December 11, 2005 Author Share Posted December 11, 2005 If anyone knows another web programming language (such as javascript) that this can be done in, please let me know. I really need to get figure this out so I can continue with my project.

0 Vlad Posted December 11, 2005 Share Posted December 11, 2005 I highly doubt you're going to find anything in the interpreted language world that will be able to do symbolic math to any level of serious detail. That includes things like bash, php, javascript, etc. Now, what you might be able to do is write a web frontend to something like mathomatic (http://www.mathomatic.com), or another open source tool capable of doing symbolic math. Might be a good idea to search freshmeat or sourceforge for something like that.

0 kingpuka Posted December 13, 2005 Author Share Posted December 13, 2005 Well, I'm making progress! :D I've found an integral approximation method that I can code easily in php. It's called Simpson's Rule. An example of a javascript function of Simpson's Rule can be found here. I hope this helps anyone else out who was looking to do a similar thing. I'm still looking for a way to calculate the derivative, and also a way to analytically take an integral.

It's gonna be hard, but just so you know: http://integrals.wolfram.com/index.jspSomeone did it :p And rather well too. Good luck!
