Quartic formula
For the general quartic:
You never see the 4 roots of a quartic given in terms of its coefficients. Here it is:
The roots now are:
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.

Re: Quartic formula
It seems impractical to remember it, but it is a nice formula..
The limit operator is just an excuse for doing something you know you can't.

Re: Quartic formula
It is for reference only. There are numerical means that are superior. I just had fun with the derivation.

Re: Quartic formula
Quartic formula? I thought it was a quadratic formula. Or are they different?

Re: Quartic formula
Quartic formula is very different, see post #1.
The quadratic formula solves quadratics, the quartic, quartics.

Re: Quartic formula
Yup. That is way out of the range.
