Solution of Sondow`s problem: a synthetic proof of the tangency

... The tangent line of a parabola at either endpoint of its latus rectum forms an angle of π4 with the latus rectum. As such, parabolas G1 and G2 share the same tangent at C1 , and similarly parabolas G2 and G3 share a tangent at C3 . At cusp C2 , however, we obtain two different tangent directions. On ...

Getting Started with Precalculus Equations of Parabolas

... Students work with parabolas whose vertex is on the origin as well as off the origin and they work with parabolas that open not only up and down, but also to the left and to the right. For these, they graph the parabola by writing two functions. Students will derive general equation for parabolas, f ...
