Hi everybody,

Some of our Advanced Math students are learning how to manually graph complex equations.  These from simple linear equations to quadratic equations, to higher ordered polynomial equations, and even through exponential equations.  Developing the intuition to do this manually is very important, our students often need a quick check to see if they are getting it right.  A quick graphing tool is also a great way for a student to play with variations in the equation and immediately see the change in the graph.  A graphing calculator is a great tool for this, but one costs about $100.  Fortunately there are free versions online.  Click on Graphing Calculators to learn more, and for the URL that will connect you to a free online graphing calculator.
