An interactive iPad app for graphing circles, ellipses, parabolas and hyperbolas
Are you interested in learning about graphing common geometrical equations? Do you have trouble remembering the formula for a circle, ellipse, parabola or hyperbola? This iPad app allows you to interact with these equations in a dynamic intuitive way. Use sliders to dynamically modify the formula's and see the graph update to reflect your changes. Got it down pat? Try the Quiz Me mode and to answer questions about your formula by touching the right point on the graph. Need a hint? Switch back to the Show Me mode or bring up the list of point values.

What's New in Version 1.8
Great, but could be better
This is an amazing app. It is very helpful and though I've not tried all of the features yet it seems promising so far. Instead of scroll bars for adjusting the m and b in a line though, it would be easier to have a way to input a number so you don't have to scroll accurately down the the tenths place. Otherwise I would recommend this app if you like to do algebra on a device!
