I'm trying to plot an exponential graph to show what happens when a capacitor is charged in a series resistor capacitor circuit.

I can do it on paper but would like to show it on my Prime. Can anyone help?

The formula I'm using on paper is Vc=Vs(1-e^(-t/RC)). This is documented throughout the Internet.

I'm trying to produce the curved graph produced as the capacitor charges and as a new user to graphing calls, am unsure of where to start. Can anyone give me a friendly nudge?

Here's how I did it:

1) Click "Apps" and select "Function".
2) In the "Symb" view, enter "V*(1-e^(-X/(R*C)))"
3) In the "Home" view, store values in variables V, R, and C. For instance "V := 15", "R := 500", "C := 1E-6"
4) In the "Num Setup" view (Shift + Numb), set the Num Start to 0 and the Num Step to 0.00001.
5) In the "Plot Setup" view (Shift + Plot), set X Rng to 0 to 0.003, Y Rng to 0 to 20, and X Tick to 0.0005
6) Now click "Plot"
