Question

prove that the tangents and normal at the end the latus rectum of a parabola form the sides of a square.

Answer 1

we would need to know what a lactating rectum is ...

Answer 2

.... oy that sounds bad lol

Answer 3

the tangents can be determined by taking a derivative; the normal is just the negative reciprocal of the tangent ... those are perp in and of themselves; if normals cross at perps and tangents cross at perps we should have a square
