angle FPF by the linePT, then PT is the tangent at P. Draw PG perpendicular to PT, then PG is the normal. Example.—The transverse axis of a hyperbola is 2j and thedistance between the foci is 2-|. Determine the conjugateaxis, the asymptotes, and draw a portion of the curve. Draw the tangent at any… … 109. Problem.—To construct a hyperbola, having giventhe asymptotes XX, YY, and a point P on the curve. Through the given point P draw lines PAf, PN ofindefinite length, parallel to the asymptotes. Through the point O, where the asymptotes intersect,draw a series of radials cutting the lines PM, PN…
