So, very often for things that I'm toying with, I want to have a polynomial that meets certain criteria. For most applications in the past, I have sat down and figured it all out by hand.
Today, I was having trouble getting the conditions that I wanted specified enough to get the sort of polynomial that I was expecting. After finding the coefficients for several sixth degree polynomials in a row, I figured I should instead be able to do something like this with the proper lisp:
That's all done now. So, for the record, the above is:
Which is still not quite what I'm looking for for this application, but it's close.
