“Convex” polynomials Wait, without $p(x) = x \in \mathcal{C}$, $\mathcal{C}$ becomes uninteresting. |

Solving systems of linear equations using matrices, 3 equations, 4 variables And there can be some 0s on the diagonal of a triangular matrix. You might encountered some system of linear equations which has no solutions or infinite solutions. |

Solving systems of linear equations using matrices, 3 equations, 4 variables The important thing when trying to solve a system of linear equations is to make row echelon form. |
