Graphing with Google

As a former math teacher, I can remember trying to attach the graphing calculator to the LCD projector or putting it under my expensive document camera so I could show my students the visual representations of an equation.  What a mess!  A few years ago, I came across a Google blog post that described how to quickly graph equations without wasting time with expensive equipment.  A short time after that, it got better.  Google added 3-D graphing.  Math classes would never be the same.  No more graphing calculator adapters/connectors, document cameras, or homemade whiteboard grids.  Teachers and students can quickly use the Search bar to generate beautiful graphs and keep the math conversation moving without fumbling over technology equipment.

It's simple.  Type an equation in the Google Omnibox or Search box and hit Enter.
If you need to other equations, you can separate them using a comma (you can add up to four equations).

Get crazy by using trigonometric, logarithmic, and/or exponential functions.

Try graphing a 3-dimensional figure using x, y, and z axes.

Wow, math class just got more exciting!
