Actually, you don’t need calculus to derive the equations for capacitors. The trick is to use electric charge, not current, and the definition of capacitance, C = Q/V. When the capacitors are connected in parallel, the charge supplied by the source is distributed between the two capacitors, thus Qs = Q1+Q2. When in series, the source pushes a charge into C1 which pushes the same charge into C2 which finally pushes the same charge back to the source, thus Qs = Q1 = Q2. With just a little algebra, the equations are yours.
Note: The calculus buffs would remind us that charge is just the integral of current, so I guess the calculus is there, just hidden!

So at 1:36 when you you were talking about the remote going too far away, for a moment I expected you to toss it off the roof.

The engineers at Sparkfun were too busy figuring out how to create the CreeperBot, that no one asked if they should build the CreeperBot.
