Re: Define the intersection points of polynomials

point is (5,6)


In mathematics, you don't understand things. You just get used to them.

I agree with you regarding the satisfaction and importance of actually computing some numbers. I can't tell you how often I see time and money wasted because someone didn't bother to run the numbers.

Re: Define the intersection points of polynomials

You gave me one whole quadratic and a point, and I asked for the first coefficient of 4 quadratics and a point for each of the quadratics.

To be honest it was not.

Because until today,

I thought that the previous problem was intractable.

did you use matlab?

Re: Define the intersection points of polynomials

hi bobbym

Well, either you come up with more problems or you admit I didn't just get lucky. So, what will it be? smile

Hi Herc11

I used Mathematica.

Hmmm, did you really think I thought that was luck?!

See post #66.

You used to be someone I could joke with. I am sorry, I did not notice the change. It will not happen again.

I do not see why you say "I told you.?" If you have read my earlier posts I was saying that he needed more equations or more information from post #2.

Re: Define the intersection points of polynomials

anonimnystefy,

So, if the polynomials were of 3 degree in order to define the intersection points 6 degree 3 polynomials will be demanded?

Is that correct?

Re: Define the intersection points of polynomials

For equations of 3rd degree you will need more than one point. Two points per cubic should be enough.
