Esteemed Budd and Sungwin, Your collection of examples of the use of the quadratic equation is Excellent. My congratulations to you for this collection. We found it while writing our article “Visualizing Properties of a Quadratic Function Using Torricelli’s Fountain” which was published in The Physics Teacher. We cited your collection in our article.
