What is focal chord?

Rahul Saxena

If a line be drawn through the focus and parallel to the directrix, it will intersect the parabola at two points that lie a distance 2 p from the focus. The line segment connecting these two points is called the focal chord.

What is latus rectum?

Ankit Pushp

JEE/Board Maths Tutor

In any conics (i.e., parabola or ellipse or hyperbola ), a line passing through its focus and parallel to its directrix is called the latus rectum. For example, in parabola: square of y=4ax, the equation of the latus ractum y=a and its length=4a; in ellipse: square of (x/a) + square of (y/b)=1, a>b, the equation of the latus ractum y=ae, -ae and its length = 2(square of b)/a; in hyperbola: square of (x/a) - square of (y/b)=1, the equation of the latus ractum y=ae, -ae and its length = 2(square of b)/a;

Find the equation of the parabola whose focus is (1, 1) and the tangent at the vertex is x + y = 1?

Ankit Pushp

JEE/Board Maths Tutor

Since it is passing through focus(1,1) x-y+L=0=>1-1+L=0=>L=0. x-y=0;x+y=1; by solving these 2 equations we get:-x=1/2;y=1/2.
