यदि परवलय के बिंदु `(bt_(1)^(2),2bt_(2))` पर खींचा ज्ञात अभिलम्ब परवलय को पुनः बिंदु `(bt_(2)^(2),2bt_(2))` पर मिलता है तब :

The normal at the point (bt_(1)^(2), 2bt_(1)) on a parabola meets the parabola again in the point (bt_(2)^(2), 2bt_(2)) , then :

If the normal at the point ( bt_(1)^(2), 2 bt_(1)) to the parabola y^(2)= 4bx meets it again at the point ( bt_(2)^(2), 2 bt_(2)) , then-

The normal at the point (bt_(1)^(2),2bt_(1)) on the parabola y^(2)=4bx meets the parabola again in the point (bt_(2)^(2),2bt_(2),) then

The normal at a point (bt_1^(2) , 2bt_1) on a parabola meets the parabola again in the point (bt_2^(2) , 2bt_2) then

The normal at the point (bt_1^2, 2bt_1) on a parabola meets the parabola again in the point (bt_2^2, 2bt_2) then :

If x=at^(3) ,y=bt^(2) , then find (dy)/(dx) .

The point (at^(2),2bt) lies on the hyperbola (x^(2))/(a^(2))-(y^(2))/(b^(2))=1 for

If S^(2)=at^(2)+2bt+c , then the acceleration is :
