Sorry, no etymologies found.
(that is, our quadratics are monic), to make our calculations easier.
Attempts to fit other functions, such as quadratics, other polynomials, logarithmic functions and exponentials all produced very small R-squared values.
For example, after I read a recent post by a Sam Shah about visually representing quadratics to see how many are factorable over integers, I started thinking about some ways to drive that point to students.
I described about 4 different ways that it could be done and even created a tool to visualize quadratics factorization, but unless someone comments or e-mails me, I'm basically in the dark.
When I studied quadratics deeply - by writing a logo program to teach quadratics behaviouristically - I was able to teach them more effectively.
The other good thing I discovered was what to say to someone at a party when they discover you are a maths teacher and come up to you and say, "they taught me boring quadratics at school and I am a successful businessman and have never used quadratics ... what a waste of time".
I remember dealing with quadratics in algebra a lot.
Non-monotonic non-linearity upside down quadratics with a maximum in the range in question – the underlying issue to Divergence poses different problems than monotonic non-linearity for example.
Currently, JT is agonising about this and I left a comment on his blog because I went through a similar agonising about breaking down the wall between behaviourism and constructionism when developing quadratics drill software in logo for my students
Nevermind the early IR hacks that let students beam test-answers back and forth during exams, the important thing was how much you could learn by having ready access to a graphing calculator while doing quadratics and the like.
