Solve the system of $$n$$ equations with unknown $$x_1, x_2, ... , x_n$$, for $$n\ge 2$$:

$$2x_1^3 + 4 =x_1^2 (x_2 +3)$$
$$2x_2^3 + 4 =x_2^2 (x_3 +3)$$
$$......$$
$$2x$$n-13$$+ 4 = $$$$x$$n-12$$(x_n +3)$$
$$2x_n^3 + 4 =x_n^2 (x_1 +3)$$

Can you help me?
 
Physics news on Phys.org
The symmetry of the equations led me to wonder what would happen if all the variables were equal. In that case, there are two solutions. $x_j=2$ is a double-root, and $x_j=-1$ is a single root. I don't think there is any guarantee that these are the only solutions, but you can see by inspection that they both solve the system.
 
Thread 'Derivation of equations of stress tensor transformation'
Hello ! I derived equations of stress tensor 2D transformation. Some details: I have plane ABCD in two cases (see top on the pic) and I know tensor components for case 1 only. Only plane ABCD rotate in two cases (top of the picture) but not coordinate system. Coordinate system rotates only on the bottom of picture. I want to obtain expression that connects tensor for case 1 and tensor for case 2. My attempt: Are these equations correct? Is there more easier expression for stress tensor...
