cross_product_length

Length of the cross product between \(\vec u\) and \(\vec v\).

Symbol:

norm(cross(u, v))

Latex:

\(\left \Vert \left[ \vec u, \vec v \right] \right \Vert\)

Dimension:

any_dimension

first_vector_length

Length of \(\vec u\).

Symbol:

u

Latex:

\(u\)

Dimension:

any_dimension

second_vector_length

Length of \(\vec v\).

Symbol:

v

Latex:

\(v\)

Dimension:

dimensionless

angle_between_vectors

angle between \(\vec u\) and \(\vec v\).

Symbol:

phi

Latex:

\(\varphi\)

Dimension:

angle

law

norm(cross(u, v)) = u * v * sin(phi)

Latex:
\[\left \Vert \left[ \vec u, \vec v \right] \right \Vert = u v \sin{\left(\varphi \right)}\]
