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