First of all thanks everyone so much for your attention.
The method i have to use is indeed the one BOB linked to (the one at WIKIPEDIA - i am not allowed to post links!).
So, I can use it for a system of linears, with ease, but i have no idea how to apply it on a system like the one i presented!!
Maybe some trick is required!?
I would be so gratefull, if someone has a hint!
this forum seems so nice!
Trigonometrical equation System. Numerical analysis! pls HELP!!
Can you please help me solve this system with, Jacobi method?!
I dont know how to use the Jacobi method, in cases other than polunomial systems!
It can't be that hard, but i dont know what to do!!
