### Great app and concept

This is an awesome app that lets you see exactly what each coefficient does in polynomials of up to third dree. I used it in tutoring and my students found it really helpful.

There could be some improvements: the magnitude of the coefficients isn't easy to adjast exactly as you want, so having an option to type them would solve this problem. I wish the variables were reversed: the way we learn in the US is ax^3 + bx^2 + cx + d. And also maybe an option of chosing a 3rd order or 2nd order plynomial. This would make the app much more intuitive.

### Brings equations alive!

I've been looking for a good app to help introduce my daughter to algebra -- visually. This one is simple but very elegant! You have 4 slide controls to control the settings of a,b,c,and d for an equation in the form: ax^3+bx^2+cx^x+d. As you move a slider the graph morphs, moves, and twists at the same time. With this you can see every imaginable graph of line, hyperbola, and beyond ... And how the graphs interrelate. You can watch as a slight change in variables affects the graph ... Sometimes subtly and sometimes dramatically! This is quite cool and I thank the author for creating and sharing it!
