Consider the parabola y^(2)=12x and match the following lists :

Answer»


Solution :`atoq,btos,c to p,d tor`.
The equation of tangent having slope m is
`y=mx+(3)/(m)`
The line 3x-y+1=0 is tangent for m=3.
The equation of NORMAL having slope m is `y=mx-6m-3m^(3)`.
The line 2x-y-36=0 is normal for m=2.
The CHORD of of contact w.r.t any POINT on the directrix isthe FOCAL chord which passes through the focus (3,0).
The line 2x-y-6=0 passes through the focus.
Chord which subtend right angle at the vertex are CONCURRENT at point `(4xx3,0),i.e.,(12,0)`.
The line x-2y-12=0 passes through the point (12,0).
