I want to practice problems for applications of hyperbolas. I am having trouble finding a website so that I am able to practice these problems. Does anybody have a website they can recommend?
The question I was given is like this?
A curved mirror is placed in a store for a wide angle view of the room. the right hand branch of x squared over one minus y squared over three equals one models the curvature of the mirror. a small security camera is placed so that all of the 2-foot diameter of the mirror is visible. If the back of the room lies on x=18, what width of the back of the room is visible in the camera?
