TRISECTRI X, a curve which is a variety of the limacon of Pascal, and named from its property of trisecting an angle. The polar equation is r= I -f - 2 cos 0 and the form of the curve is shown in the figure. To trisect an angle by means of this curve, describe a circle with centre 0 and radius OE, and let the given angle which is to be trisected be laid off from OE and cut the circle at S; let the chord ES cut the trisectrix in J. Then OJ trisects the given angle.
