Adding Math Text to Activity Builder Screens

You can add beautiful, formatted math text to write equations, numbers, and more to Activity Builder screens. To get started, add a "Note" to a screen. Select the "f(x)" button in the bottom right hand corner. 


This will bring up a text box for you to enter your math text. You can type just as you do in the calculator. For example, typing y=x^2 will yield this:

Press enter after you're done entering your equation. The equation will be enclosed in `` tags. Do not remove those tags or the math text will be removed and replaced with plain text. Click "Done" after you have completed your note.

    How can we add calculus notations to an input panel. Is there an equation editor somewhere?

    Thanks, Jean

    Hi Jean! Thanks for your question. Some calculus notation is currently supported (e.g., try typing int or f'(x) or d/dx). Other notation is not (yet) supported (e.g., lim). Stay tuned for more updates!

    What about square roots and bases of logs?

    In a note, I'd like to add an expression involving a limit, such as `\lim_{\Delta x \to 0}\frac{F(x)}{\Delta x}`. Is there a way we can access raw $\LaTeX$?

    Hi, Desmos - Can you add limit in your Graph Editor?

    Ex:    lim(x)x->0
