Practical Uses for Computing ParabolasDate: 1/30/96 at 9:27:45 From: Anonymous Subject: Computing parabolas Hello kind sir, I have a question regarding parabolas. Could you give me at least three practical uses for computing parabolas? Can you also tell me the significance of computing the parabola in regard to its application? I'm hoping for your speedy response since my brother's future in his math class depends on it. Thank you in advance for any help you can extend.

If an object is thrown in a gravitational field and the resistance of the air is not considered, its path lies along a portion of a parabola. This alone would make the study of parabolas worthwhile. 2,3,4,5. The reflectors of headlights and flashlights, as well as solar heaters or distant listening devices, not to mention telescopes, are based on the reflection properties of parabolas. A beam of light parallel to the axis of a parabolic reflector will be reflected through the focus of the parabola which is the intersection of the reflector and the plane containing the axis of the reflector and the beam of light as it first approaches the reflector. Many of these applications can be found in a good encyclopaedia. -Doctor Jerry, The Math Forum Check out our web site! http://mathforum.org/dr.math/ |
