For R=2 ohms plot Va as a function of V1 and V2. For V1 and V2 are between 0 and 20 volts. Second part is to find the values of V1 and V2 that produce Va = 0 while minimizing the total power absorbed by the resistors (hint you may want a second plot of total power as a function of V1 and V2)...

Fist, this is for a personal project of mine, I've been out of school for some time, and all my old math skills seem to have abandoned me. For that reason, and because I have to translate anything I learn into functions compatible with c#'s math library, it'd probably be best to keep any answers...

Hey. Im trying to make a plot of a function, and was wondering if there was a way to plot it based on the equation that defines the function rather than a set of points on the curve? i.e. instead of plot(x,y) for a set of (x,y) coordinates, id like to just specify the defininig equation...
