# Grassmannian
For other uses, see Grassmannian (disambiguation).
In mathematics, the Grassmannian Gr(r, V) is a space which parameterizes all linear subspaces of a vector space V of given dimension r. For example, the Grassmannian Gr(1, V) is the space of lines through the origin in V, so it is the same as the proje... | {} |

Let $z_1, z_2$ be nonzero complex numbers such that
$z_1^2 + z_2^2 = \sqrt{2}z_1 z_2$.
Show that $| z_1 | = | z_2 |$ and find $Arg{(\frac{z_1}{z_2})}$.

Sorting of h parts in distance of the elements of h. Merging the parts for descending order of h values with insertion sort. This means the elements gets moved over a greater distance. Typical: $h(k+1) = 3 * h(k) + 1$
