d point A as the centre of the circle moves along a fixedline OX. As the intersection of the circle and secant will give twopoints P, P, one above and the other below the fixed line, itis evident that during the motion of the circle these pointswill generate a curve with two branches. The upper… … 1, To deduce the rectangidar equation. Let P (x, y), the intersection of the circle PPP and the HIGHER PLANE CURVES. 197 secant AOT, be any point of the curve. Let OP = OB = h,and let OA = a. The equation of the circle whose centre is at 0 (x, 0) is (x — xY -\- y^ = b^-The equation of the line AOT…
