lf `(x_1, y_1), (x_2, y_2), (x_3, y_3)` be three points on the parabola `y2 = 4ax`, the normals at which meet in a point, then

Let (x_(1),y_(1)),(x_(2),y_(2)),(x_(3),y_(3)) be three points on the parabola y^(2)=4ax if the normals meet in a point then

If P(x_1,y_1),Q(x_2,y_2) and R(x_3, y_3) are three points on y^2 =4ax and the normal at PQ and R meet at a point, then the value of (x_1-x_2)/(y_3)+(x_2-x_3)/(y_1)+(x_3-x_1)/(y_2)=

If P(x_(1),y_(1)),Q(x_(2),y_(2)) and R(x_(3),y_(3)) are three points on y^(2)=4ax and the normal at PQ and R meet at a point,then the value of (x_(1)-x_(2))/(y_(3))+(x_(2)-x_(3))/(y_(1))+(x_(3)-x_(1))/(y_(2))=

Let A(x_(1),y_(1)) and B(x_(2),y_(2)) be two points on the parabola y^(2) = 4ax . If the circle with chord AB as a dimater touches the parabola, then |y_(1)-y_(2)| is equal to
