Document 376k

Provides an overview of the four basic conic sections: parabola, circle, ellipse, and hyperbola. Formulas and explanations are provided...

full explanation please

The conic section that is being used has to be a parabola, circle, ellipse, or hyperbola.

(y+3)^2/25+(x-2)^2/16=1

Two people standing 10,000 feet apart see a lightning strike. One person is 5500 feet farther from the lightning strike than the other. The possible locations form a hyperbola with the two people...
