[If thecircle passes through the origin, the equation must be satisfied byx = Q,y = 0.] 6. In the equation of the preceding question what are the inter-cepts on the axis, the circle passing through the origin? 7. Find the equation of the circle which passes through the origin,and cuts off lengths… … P and Q being successive points of intersection ofthe secant with the curve, if Q move along the curveso as to approach indefinitely close to P, the limitingposition of PQR, say PT, is called the tangent at P;and P is called the point of contact of the tangent PT. 86 Analytical Geometry.
