Echo's rich text editor allows users to add math expressions, formulas, and equations. For example, Echo will convert the text string: sum_(k=1)^n k = 1+2+ cdots +n=(n(n+1))/2
Echo's Insert Equation feature supports three languages:
- Ascii Math (preferred)
NOTE: It may be necessary to add cdnjs.cloudflare.com to your district's website whitelist for this feature to work.
Adding Math Expressions
To insert a math expression into the Rich Text Editor:
- Place your curser at the desired location and click the Insert Equation button in the Rich Text Editor's menu bar.
- Enter the Ascii Math, LaTeX, or MathML text string.
- Use preview pane to confirm that the equation is correct.
- Click Save when done.
