If `r_(1), r_(2)` be the length of the perpendicular chords of the parabola `y^(2) = 4ax` drawn through the vertex, then show that `(r_(1)r_(2))^(4//3) = 16a^(2)(r_(1)^(2//3) +r_(2)^(2//3))`

If r_(1) and r_(2) are the lengths of perpendicular chords of the parabola y^(2)=4ax drawn through the vertex,then (r_(1)r_(2))^((4)/(3))

If r_(1) and r_(2) are lengths of perpendicular chords of the parabola drawn through vertex then (r_(1)r_(2))^((4)/(3)) is

Prove that r_(1)+r_(2)+r_(3)-r=4R

Prove that r_(1)+r_(2)+r_(3)-r=4R

Show that (r_(1)+ r _(2))(r _(2)+ r _(3)) (r_(3)+r_(1))=4Rs^(2)

Show that 16R^(2)r r_(1) r _(2) r_(3)=a^(2) b ^(2) c ^(2)

show that r_(2)r_(3) +r_(3) r_(1)+ r _(1) r_(2)=s^(2)

In a DeltaABC, show that r_(1)* r_(2)* r_(3)*r=Delta^(2).

A and B are two points on the parabola y^(2) = 4ax with vertex O. if OA is perpendicular to OB and they have lengths r_(1) and r_(2) respectively, then the valye of (r_(1)^(4//3)r_(2)^(4//3))/(r_(1)^(2//3)+r_(2)^(2//3)) is

" (i) Show that "r+r_(1)+r_(2)-r_(3)=4R cos C
