The Geometers Sketchpad Dynamic Geometry Software for Exploring Mathematics NIB #Software

Find curves in monuments, buildings and water jets and fit a parabola to them using dynamic geometry software." Quadratic graphs are everywhere you look. They can describe the paths of rockets, balls and jets of water. Because of their symmetry you will see parabolas in bridges, buildings, sand dunes... Understanding their equations is hence hugely important in the fields of engineering and science. This...
