Not suitable for this site | |
| Oct 24, 2015 at 22:38 | comment | added | user9072 | @JoeSilverman who knows what OP actually need to do? They say "Because I have an exercice , to solve my exercice I need parametrisation of this equation." Why do they need this? What are they actually trying to achieve? Maybe OP is actually on the wrong track to solving their HW. Furthermore, to me "hard" is not the only or even main criterion to decide suitability. (On the other hand the mere fact it is related to HW would not bother me, if it were only clear what exactly is to be done.) I voted to close. | |

| Oct 23, 2015 at 20:36 | comment | added | Joe Silverman | For those who are voting to close, I agree it's not great for the OP to say it's a homework problem; but it actually seems like a very hard problem, at least with the minor generalization of describing integers solutions for $x^4+y^4+z^4=at^4$ for different values of $a$. | |

| Oct 23, 2015 at 20:29 | comment | added | user81854 | Finally I found reference for parametrisation of x^4+y^4+z^4=t^4+u^4 zone | |
| Oct 23, 2015 at 20:16 | comment | added | Geoff Robinson | Well yes, but that does not parametrize the solutions of $x^{2}+y^{2}+z^{2} = 2t^{2}$. | |

I'm letting you know that math.overflow is not supposed to be for asking for help with homework (note that I did not say you were asking for a solution). I'm sorry if you think it's patronizing, it is not intended to be. There are other sites that are more welcoming to that kind of question (e.g., math.stackexchange). P.S. When replying to someone specifically, they will get a notification if you use the "at" sign, @Geoff for example, will produce a clickable link and a notification to the user addressed, if that user has posted comments or the answer you are replying to.

| Oct 23, 2015 at 20:05 | comment | added | user81854 | Geoff , for z=t we get pythaorean triple x^2+y^2=t^2. | |

| Oct 23, 2015 at 19:32 | comment | added | user81854 | Dear Arturo , I just ask if it is known parametrisation of the equation I posted. I don t ask solution of my homework. Don t patronize people. | |
| Oct 23, 2015 at 19:26 | comment | added | Arturo Magidin | However, Mathoverflow is not for asking for help with your homework problems... | |
| Oct 23, 2015 at 19:25 | comment | added | Geoff Robinson | Might it be easier to start with $x^{2} + y^{2} + z^{2} = 2t^{2}$? | |
| Oct 23, 2015 at 19:22 | comment | added | user81854 | Because I have an exercice , to solve my exercice I need parametrisation of this equation. | |
| Oct 23, 2015 at 19:05 | comment | added | Arturo Magidin | What is the context? Why are you interested in this particular equation and in a parametrization [of its solutions?] ? | |
