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 = ax^3 + bx^2.

Details:

• units are in mm
• Range(x) = -55 to 45
• a = 50/(45^3), b = 50/(45^2)
