Fastest proof for theory that parallel rays entering parabola hit focus?
Q. Please, no calculus except derivatives, if possible. We've talked about this property in class about a million times (i.e. how satellite dishes work), but no teacher has ever provided a proof. I came up with one a while ago, but it's too lengthy for my taste (~1 page). The parallel lines I'm referring to are the ones that are parallel to the line containing the vertex and the focus, and in many cases, the y-axis.

A. For this proof, you're going to need to know vectors and a tiny amount of multivariate differential calculus. Consider a curve (like a parabola), and the tangent vector, S, on this curve at the point (x,y). 1) Lemma: If there are two vectors of unit length, u_1 and u_2, such that the dot product (scalar product) S.(u_1 + u_2) = 0, then u_1 and u_2 make equal angles to the normal to S. Proof: If the dot product is 0, then since S is perpendicular to (u_1 + u_2), the normal to S is parallel to (u_1 + u_2). But then: cos(u_1, u_1 + u_2) = u_1.(u_1 + u_2)/(mag(u_1)*mag(u_1 + u_2)) = (u_1.u_1 + u_1.u+2)/(1 * mag(u_1 + u_2)) = (1 + u_1.u+2)/(1 * mag(u_1 + u_2)) = (u_2.u_2 + u_1.u+2)/(1 * mag(u_1 + u_2)) = (u_2.u_2 + u_1.u+2)/(mag(u_2) *… [cont.]
