Is your feature request related to a problem? Please provide a clear and concise description of what the problem is. Ex. I'm always frustrated when [...]

I cannot find a way to plot a sequence made with u_n and v_n into (x,y) where x=u_n and y=v_n
this would be useful for plotting phase portraits and other calculators do allow this

Please describe a single improvement per issue. Feel free to open multiple issues though!

I would like the toolbox to have u_n and v_n as an option so I can plot it into the grapher

Hello @MrH-nerd ! Thank you for your request !

In the Sequences app, you can only plot each sequence against n.

But to plot u_n against v_n for example you can use our Regression application.

First define the sequences u_n and v_n in the sequences app, then use the fill with formula option for the regression column X1 and input X1=sequence(u(k),k,10) and then do the same for Y1 with v_n.
Here is a screenshot of how to input them:

You can then check the Graph tab of the regression application and see X1 plotted against Y1 and thus u_n against v_n.
