1. An electrical circuit for the simultaneous solution of three equations comprising: three ganged potentiometers coupled to receive a common first voltage signal and to be driven by a first angular driving means; a pair of ganged potentiometers coupled to receive a common second voltage signal and to be driven by a second angular driving means; summing networks coupled to the outputs of each of two of said three ganged potentiometers and an output of each of said pair of said ganged potentiometers, respectively, to produce first and second sum voltage signals on outputs thereof, and a summing network coupled to the output of one of said three ganged potentiometers and the output of one of said first and second summing networks to produce a third sum voltage signal on an output thereof; attenuating means coupled to attenuate said third sum voltage signal in accordance with a third angular driving means, the attenuated third sum voltage signal output of said attenuating means coupled to control said second angular driving means whereby the first, second, and third angular drive means and the various voltage signal inputs coupled and arranged aforesaid provide three simultaneous equations of analog voltages in said three potentiometers and summing networks to produce said first and second sum voltage signal outputs as the solution in analog voltages.
