How do you hyperbole with a flashlight?
I looked through my math book and there was this activity that she has you told to take a flashlight and tilt at different angles to form a circle, ellipse, parabola, and hyperbola. I understand the first three but how can you make two branches on a beam of light?
I think they only speak half a hyperbole, as in positive values only. Yes, a hyperbola has two complete solutions, so it is a mirror image across an axis. But it is commonly described as only half of this diagram. Flashlight perpendicular to the wall is a circle. At one corner of the wall is an ellipse. Against the wall up or down parabola. Against the wall pointing horizontally hyperbole.
