Hay dere. I've come across a nonlinear equation system which i've tried solving in maple through matrices. Maple's own solve function for systems didn't work out (just threw back gibberish at me which i wasn't able to simplify (root of Z etc)) and i really don't know how to approach the problem. Any suggestion on how to solve it would be appreciated.

The problem is as follows:

0 = 22 - 44t + 216t - 66u - 450u + 362u
0 = 150 - 300t + 185t - 450u + 795u - 495u

Hello. Im courius if there is any (easy) way in Maple to do a Chebyshev curve fitting. I havent been using Maple mutch and I cant say that I really understand how the chebyshev approximation works, but i want to do a comparison between the Least Square Criterion (with the funktion: a*x + b) and Polynomial Interpolation and the Chebyshev Approximation (with the exp: a*x + b). The Least Square and the Polynomial are both options in the Curve Fitting Assistant (in Maple 11), but not the Chebyshev (is it becouse its somehow inferior to the least square?). And by the way, please note if I write anything wrong (spelling, grammar, etc etc..). English is not my native language.
