Daily Equation #17 - y = a*x^3 + b*x^2

This is Day 17 of my collection of printable equations. To see the whole collection, go to: http://www.thingiverse.com/thing:227210

This will be last printable equation for a while. Real life's caught up and I don't have enough time. I may post a new equation once in a while, but I'm not sure. In a few days, I will post the source code I used to generate the oscad files.

Continuing the series of polynomials today, with y = a*x^3 + b*x^2.

Details:
- units are in mm
- Range(x) = -5
