Parallelepidial Product - Calculation of Coordinates

A B C D E F G H I J K L M N O P Q R S T U V W X Y Z overview

If the vectors $ \vec{u}$ , $ \vec{v}$ and $ \vec{w}$ span a proper parallelepiped, then every vector $ \vec{x}$ can be represented by a linear combination

$\displaystyle \vec{x} =
\alpha \vec{u} + \beta \vec{v} + \gamma \vec{w}

with the coefficients

$\displaystyle \alpha = \frac{[\vec{x},\vec{v},\vec{w}]}
\gamma = \frac{[\vec{x},\vec{u},\vec{v}]}
