on pre-sents itself, the example of the last paragraph may be stated,—Having given theequation x^ — Qxy + 2/^ — 6x -{- 2y -(- 5 =. 0, as the equation of a locus referred torectangular axes, required to find the position of a new pair of axes to which, whenthe locus is referred, its equation will… … ScH.—As tliGfo77n (not the degree) of the equation of a locus, depends ina large measure upon the situation of the axes, or upon the system used, itwill be readily seen that a set of axes in some particular position, or someparticular system of co-ordinates, may be best suited to one class of…
