Help with graphing Bessel function and its sums - RickyFlips - 07-08-2020 08:45 PM
I'm new-ish to HP Prime and hoping someone can help me figure out how to graph a Bessel function and its sums. I've already put about two hours into trying to figure this out on my own using the documentation, built-in help, and Google results, but no joy.
Here's what I've got in the Sequence app:

When I click the Plot button, I get this, which obviously isn't correct:

My understanding is that, in order to sum the sequence, I have to wrap it inside a function, so here's my attempt at that, which causes the calculator to reboot:

Trying this a different way without graphing, I entered it as an expression, but got syntax error:

Any help would be very much appreciated!

Use the CAS to handle symbolic operations like this summation:

It doesn't work in home because the X variable gets evaluated to whatever is stored in it.
Edit: You can place it in the Function app like this:
F1:=unapply(Ans,x);
Then check it in the symbolic view and plot.
