Error: Cannot store a list in a list

Questions

Hi All –

I’m trying to graph a sequence of partial Riemann Sums, but Desmos is giving me a “Cannot store a list of number in a list” error.

Here’s my attempt: https://www.desmos.com/calculator/qdqljk7oqo

Is this fixable?

Thanks!

There are some sticky workarounds for storing a list within a list, but maybe an example of the same idea would be useful.

I made this a few years back:

Hi Vince —

Thanks very much for your showing me your workaround. Unpacking your code is a bit more work than I want to do right now, especially since I expect the graph that will display these results will get about 30 seconds of airtime in my class tomorrow. But I do appreciate your willingness to share, and I plan on digging in and trying to figure out what you’ve done when time permits.

Thanks again!
