Focus and Directrix of a Parabola 2
Continuing from a previous video, Sal takes the discussion of the focus and directrix of parabola further. Given the parabola, y=x2, he derives the focus and directrix by matching parts of the equation he found earlier. He then, comes up...

Parabola Focus and Directrix 1
Starting with a point (focus) and a line below the point (directrix), in this video, Sal tries to find the set of all points (locus) equidistant to the point and the line. He shows, using the distance formula, that indeed, we have an...

Parabola Focus and Directrix 1
In this video, starting with a point (focus) and a line below the point (directrix), Sal tries to find the set of all points (locus) central to the point and the line. Using the distance formula, he shows that we have a parabola equation.
