Subject: RE: Math geeks - help neededOk, so I understand you are a PhD in math, so you are the authority.
However, should we be asking if a 3rd degree polynomial is appropriate?
We have two points, so a line between the two is the simplest "line of best fit." Since the tangent at the origin is zero, then joining these two points needs to be done with at least a quadratic (ax^2+bx+c | c=0 )
Joining these two points could be done with a 4th order, 8th order, or 21st order polynomial... so why are we picking the 3rd order?
To the OP: If you want a 2nd order equation that solves your needs, how about:
f (x ) = 0.02 * x^2
