mathman, could you clarify a bit? How are the two derivatives parameters? I don't get that. Sorry for my ignorance; where could I read further into this? I do understand why a fourth degree polynomial would be the starting point.

Edit: Sorry I get it now. What would be a more accurate way to do this?

Start by making assumptions about what the function looks like across its domain, assumptions that use a first and second derivative.

The other two equations come from knowing the values of the function at the end points (A and C) of the interval.
