SUMMARY

The discussion focuses on plotting the ordinary differential equation (ODE) y' = 3 + 2y using the TI-Nspire CX CAS calculator. The user initially struggled to plot the equation due to the absence of the variable x in the equation. The solution was to utilize y1 instead of y, as y1 is the default function in the calculator. This clarification resolves the issue of obtaining a meaningful plot from the ODE.

Hi, I'm new here. I did some research plotting the ODE of y'=3+2y without having x shows up in the equation. I can't figure it out, why the calculator does plot a harder equation but not a simple one? I can get the slope field with an equation that has an x in it. However, without x, my calculator just gives me nothing (without an initial condition setup), or a single dot (with the setup.)
So, does anyone know what to do in order to get it work?

TIA

Figured out myself, you have to use y1 instead of y, because y1 is the default function. Kind of a silly mistake...
