Let A = (0,1) and B=(-p/2,(q+1)/2) be two fixed points in a plane. Let C denote a circle with centre B and passing through A. Prove that the real roots of the
If the normals at two points P and Q of a parabolay2=4axintersect at a third point R on the curve, then the product of ordinates of P and Q is View Solution Ifa,bandcare inAP,then the straight lineax+by+c=0will always pass through a fixed point whose coordinates are (a) (1,...
