 tpowers Comment: A nice, clean webpage with a good perspective on quadratic equations (as the product of linearly-related quantities). Great lab exercises as well, I actually learned something about quadratics. Mike McMillen Comment: nice and neat. Easy to use. the lessons are helpfull DAS Comment: An excellent tool. Takes a bit of upfront knowledge to get started. Limited use with function notation.
