Abstract
The expression of the root locus by a self-conjugate equation is newly proposed as an analytical reprsentation of the root locus. The equation of the tangent at any point on the root locus is expressed in the simplest form by a self-conjugate equation. Thus both the condition for the breakaway point and the characteristic of the tangent at the breakaway point are made clear. Also the equation of the asymptote of the root locus is determined in a more detailed form than ever.
