Using the character delta?

I’m trying to use the character delta (for change in y and change in x) in a note in an activity. Is there a hotkey or code I can use? “\Delta” does not work in the function editor or in the computation layer.

I think you just need an extra backslash. Also make sure the back ticks enclose it so that it is using latex.

`\\Delta y`

Thanks. Works in the script although not in the expression editor within a note.

If you know the hotkey you can type it in, if not you can copy/paste symbols into the note
