The analytic method for plotting root loci is examined. The basic equation for this method, originally published by Bendrikov and Teodorchik in 1959, is derived in a very simple way. A second equation, which complements the original Bendrikov equation, is also derived. An example of how these two equations may be used to plot root loci using Mathematica is presented.
