Quadratic EquationDate: 6/22/96 at 22:34:20 From: Anonymous Subject: The Quadratic Equation - In Laypeople's Terms We were testing our math literacy and found that we could not recall what a quadratic equation is used for. Could you please enlighten us? We searched and searched on the Web but could not find an answer in laypeople's terms. Any insight would be appreciated. Thanks.

Seiden, whose web pages have since fallen off the web, once wrote this explanation, which you might help refresh your memory: "Where would you use it in the real world? Outside of helping you pass math, the Quadratic Equation can be very helpful. Let's say you throw a baseball up in the air to your friend. That ball follows a parabolic path, which means there is a quadratic equation involved, and you can use the Quadratic Formula to figure out how far the ball will go. You can also use it to figure out how hard you need to throw it to make it to your friend." If you need a more detailed explanation, write back with a specific question and we'll try to help you out. -Doctor Sarah, The Math Forum Check out our web site! http://mathforum.org/dr.math/ Date: 6/24/96 at 10:31:2 From: Doctor Ethan Subject: The Quadratic Equation - In Laypeople's Terms The most basic example is any time that you have an equation describing the motion of an object where there is a constant acceleration. Then you have a quadratic equation. This occurs a lot. Gravity is a good example. -Doctor Ethan, The Math Forum Check out our web site! http://mathforum.org/dr.math/ |
