What is that method?

Hi;

If you know the form you want you can curve fit.

In mathematics, you don't understand things. You just get used to them.
90% of mathematicians do not understand 90% of currently published mathematics.
I am willing to wager that over 75% of the new words that appeared were nothing more than spelling errors that caught on.

I don't follow... how will curve fitting help you factorise a^6 + 8b^6 for example?
