How to Use the Equation Editor
The WebEQ Equation Editor has been integrated into the ANGEL HTML editor. It gives editors a way to enter mathematical expressions in a web page, much as the text entry controls and buttons in typical HTML forms give users a way to enter other kinds of information.
The Insert Equation function is used with WebEQ Equation Editor, which can be used to create, save, and view complex mathematical equations in ANGEL. Equations are built up out of mini-templates. These blank templates are small squares that can be filled in.
When the cursor is in a slot, the parent template is faintly outlined in gray. Since many templates can be nested in a single equation, this helps you keep track of where you are.
The following is the WebEQ Equation Editor toolbar.
