In a discussion of "golden ratio calipers" ( www.goldenmeancalipers.com , www.quantumbalancing.com/goldenmeantemplate.htm , many others - just google it ) I was asked how to get from the classical "the ratio of the smaller to the larger, is the ratio of the larger to the whole" to 1.618. A no-more-than-H.S. math listener remarked that was the only time in his life that he had seen the quadratic formula used for anything. - John On July 31, 2012 at 8:06 PM Henry Baker <hbaker1@pipeline.com> wrote:
I can easily come up with elementary applications of square roots, but are there any (many?) elementary/high school applications of the quadratic formula?
