Important Questions on Basics of Parabola
The extreme points of the laus rectum of the parabola and . Find the equation of the parabola.

Let be a square of side length units. A line through is drawn parallel to . Point moves such that its distances from the line and the vertex are equal. If locus of cuts at and and at , then area of is

Locus of point of intersection of the straight lines (where is a real variable parameter) is

A variable parabola is drawn to pass through and ends of diameters of a given circle centred at origin and radius and to have as directrix a tangent to concentric circle of a radius . The coordinate axis being and perpendicular diameter. Find the locus of focus of the parabola

From the vertex of the parabola , two mutually perpendicular chords and are drawn. Rectangle is completed, then locus of point will be a conic such that

The slope of the line which belongs to family of lines and makes shortest intercept on , is

Let the parabolas and touch each other at . Then

If point lies on parabola whose focus lies on -axis and directrix is such that lies on curve then:

If and be the lengths of perpendicular chords of a parabola through its vertex, then


If the Cartesian co-ordinates of the point on the parabola whose parameter is is

Let be a focal chord of the parabola . If the centre of a circle having as its diameter lies on the line , then the length of the chord is

If from the vertex of a parabola, a pair of chords be drawn at right angles to one another and with these chords as adjacent sides a rectangle be made, prove that the locus of the further angle of the rectangle is the parabola

The length of the latus rectum of the parabola is

Find the co-ordinates of a point on the parabola , whose ordinate is twice of its abscissa.

Prove that the curve whose polar equation is is a parabola.

The abscissa of a point on the parabola is ; find the distance of the point from its focus.

The parabola passes through Find the length of latus rectum.

Examine whether the point lies inside, outside or upon the parabola .
