Separating Doubly Nonnegative and Completely
... For X ∈ Sn let G(X) denote the undirected graph on vertices {1, . . . , n} with edges {{i 6= j} | Xij 6= 0}. Definition 1. Let G be an undirected graph on n vertices. Then G is called a CP graph if any matrix X ∈ Dn with G(X) = G also has X ∈ Cn. The main result on CP graphs is the following: Propo ...

5-3 Unit Circle Exact Values (Degrees)
... While we can use our sandbox trigonometry to find values on the unit circle, we will generally have to round those values. However there are some exact value coordinates on the unit circle, such as the coordinates at angle rotations of 0°. 90°, 180°, 270°, and 360° (and all their multiples). 16a. ...

LINEAR DEPENDENCE AND RANK
... Another theorem of linear algebra provides a way to evaluate whether a consistent set of equations has an infinite number of solutions: a consistent system of n equations in n unknowns has a unique solution if the rank of the coefficient matrix is equal to its order, where r(A) = n. In the example h ...
