Examples:  2x1^2 + x2^2 + x3^2 - 0.5^2 = 0; and x1^4 + x2^4 + x3^4 - 0.5^4 = 0;

 

 

 

The algorithm is still being finalized.

As for me, then no, I cannot.  But I can promise, if something turns out interesting, I will definitely try  implement in Maple.

@spalinowy 
and this is only one variable s. Listen to the first advice by Mariusz Iwaniuk.
( Do not mock your computer.)

@spalinowy 
You said that you are solving a system of 5 equations, right? Which variables do you want to find? Only s? In this case, I'm afraid you do not very well do what you need, and you were given a very correct answer.
If this is not the case, then please let us know in detail what the real situation is.

Will not say  that I understand the problem, but you can build a pyramid with the help of
(Не скажу, что понимаю задачу, но строить пирамиду можно с помощью)
plottools[polygon]
>?plottools[polygon]

@Carl Love 
of course, you suggested a general approach.

f:=x->((4*x^2-4)^4)^(1/5);
evalf(f(0));

@panke  I type  ?dsolve[events] then press Enter and receive a detailed description.

@panke 
 

restart; 
dsys1 := {x1(0) = 0, x2(0) = 1, diff(x1(t), t) = 1, diff(x2(t), t) = t}; 
dsys11 := dsolve(dsys1, numeric); 
plots[odeplot](dsys11, [t, x1(t)], t = 0 .. 12);
 plots[odeplot](dsys11, [t, x2(t)], t = 0 .. 12); 
dsys := dsolve(dsys1, numeric, events = [[x2(t) = 5, [halt]]]);
plots[odeplot](dsys, [t, x1(t)], t = 0 .. 12); 
plots[odeplot](dsys, [t, x2(t)], t = 0 .. 12);

 

@nm  Information just in case, perhaps, will be useful. Look at the differences.

Example:
nops(solve([x^2+x*y-1, y+1], [x, y]));
and
nops([allvalues(solve([x^2+x*y-1, y+1], [x, y]))]);

@Adam Ledger You also missed [ ]  in my answer

@nm  You missed [] in my answer.

@Fabio92  Of course, there are fundamental differences in the construction between precision machines and manipulators. But there are materials, for example, wood, plastic, styro foam and the like, where, it seems to me, the use of a manipulator is quite possible as a CNC. That is, yes, the idea is more mathematical than technical.
Thank you for your clarification. My English exists by help a Google  translator only.

I especially thank you for your full understanding of the idea, and it's nice, because I very rarely manage to explain anything even in Russian.
