Mathematical Equation Editor Plugin - WYSIWYG Solution

Hi there,

I'm currently looking into integrating a mathematial editor/plugin with CKEditor.  The preferred solution is a WYSIWYG editor and so far we have identified WIRIS Editor.  CODECOGS requires LaTex / MathML knowledge.

However WIRIS Editor requires licensing cost and I'm wondering is there an available plugin/WYSIWYG editor for mathematical equation that can be integrated with CKEditor which does not involve any licensing cost?

Thanks.

Regards,

April
