We already have a portal to which I want to add the following functionality needs to be added:
1) Integrate an online WYSIWYG editor in a PHP page which can take care of all of complex Mathematics Symbols (e.g.: Square Root, Integration, differenciation, sigma, etc.)
2) Some minor modification/PHP coding stuff involved etc.
Has to be done in PHP. Has to be done in an urgent manner (3 days max).
Only companies with prior experience in handling editors with complex symbols need to apply for this.
