Error on expression evaluation

[Logan Lecas]

I have code that should take in two points from a form and then add an expression to the screen to calculate the distance. However, it gives an error when trying to evaluate it, but the error is fixed if a user clicks onto the expression and moves the text cursor with the arrow keys or presses space.

Hi Logan,

It seems to me that your latex isn't properly formatted so that the calculator can understand it. I believe the following is happening: Desmos is parsing the distance function not as a function, but as a bunch of variables multiplied together and (original, second) as a point, not parameters of the function. Selecting the expression and moving the cursor, or modifying the expression makes Desmos normalize the latex. This causes it to realize distance is in fact a function . Can you try changing the calculator.setExpression line to use the following latex:

`o_{distance}=\operatorname{distance}(${original},${second}})`

Note how distance is replaced by \operatorname{distance}. This makes it clear to desmos that distance is a function.

Please let me know if this fixes it!

Sincerely,
