## Finding a numerical solution to system o...

Maple 2015

I have a system of equations in several variables and I just need one numerical solution of it, I tryed to use fsolve of Maple but it always show me some errors or gives back the command as the output.

aaghulu := {-6-4*y-x-(1+y)*x+sqrt((4*(1+y))*(2+x)*(4+2*y+x)+(-(1+y)*x+2+x)^2), (2*(4+2*y+x))*(1+y)-(1+y)*x+2+x+sqrt((4*(1+y))*(2+x)*(4+2*y+x)+(-(1+y)*x+2+x)^2)-(2+y)*(-(1+y)*x+2+x+sqrt((4*(1+y))*(2+x)*(4+2*y+x)+(-(1+y)*x+2+x)^2))};

fsolve(aaghulu, {x, y}, maxsols = 1);

I will be happy if someone guide me how to do these kinds of things using Maple.

## Horner polynomial...

Maple

Of course it's easy to write a procedure to compute the ith Horner polynomial of a polynomial but I'm carious to know if there is any built-in command for doing this, I searched in help of Maple and found several ways but they convert or rewrite the input polynomial in Horner form so the output is last Horner polynomial which is equal to the input polynomial with this difference that it is written in a kind of factorization form which shows the Horner structure and ofcourse with looking at it you can read other Horner polynomials too but why not having exactly the ith Horner for the output? So is there any other command with output being the ith Horner?

## Vertical label of plot...

Maple

When I right click on a plot and add a label name for the vertical axis, it is shown in horizontal way next to it, what should I do if I want to have it in a vertical display along the axis written upward?
