Mr. Gibbins′ Triangle
Published online by Cambridge University Press: 03 November 2016
Extract
In the Gazette No. 249, Vol. XXII, Mr. Gibbins has deduced some interesting formulae connected with the triangle ABC, of which the side BC is given by L = lx + my +n= 0 and AB, AC by the equation
The equations of the circles in § 3 of Mr. Gibbins’ note are very elegant indeed. But, in principle, it does not seem desirable to have recourse to pure geometry in dealing with problems in algebraic geometry. The algebraic analysis is not difficult. It is not necessary to resolve S into factors. Let us assume that S≡vw, where v ≡ l2x + m2y + n2 and w ≡ l3x + m3y + n3.
