| Technology has transformed the way we look at mathematics. Working
with linear equations was once a matter of extensive algebraic manipulation,
or painstaking drawing of accurate graphs. Now a graphing calculator
can produce the graph and allow numerical investigations of graphs in seconds.
A limitation of the graphing calculator comes when exploring situations where modifying the equations to find a solution is a useful problem solving strategy. This web site presents a teaching activity using Geometer's Sketchpad to explore such a situation. |
