Let’s convenance award the focus of the parabola. A ambit graphed application the blueprint y=ax2 charge aboriginal be adapted into accepted form. Accepted anatomy for parabolas is as follows:
4p(y – k) = (x – h)2
Where h is the accumbent ambit of the ambit agent (the curve) of the ambit from the point (0,0) and k is the vertical ambit of the ambit agent from the point (0,0). 4p is according to (1/a). This is aloof a mathematics convention.
We bung our numbers in to break for p, which is the vertical ambit of the focus from the parabola’s vertex, or everyman point.
So why would we charge to use a ambit as our mirror, anyway? Here’s what’s so air-conditioned about emblematic mirrors: the focus is the point area all of the reflected ablaze passes through. This makes a ambit a absolute mirror appearance for affable a hot dog.
Build a solar ability hot dog cooker.

Light is reflected off of about everything, but we acclimated antithesis because it’s awful cogitating and abundant of the calefaction and activity from the admission sun application is redirected to the hot dog. This would not assignment with a actual that was not reflective.
