From Wikipedia:
Using the dot and cross products, the vector v can be decomposed into components parallel and perpendicular to the axis k, where the component parallel to k is called the vector projection of v on k, and the component perpendicular to k is called the vector rejection of v from k.
"Vector projection" is проекция вектора v на k in Russian, but I've never heard the term "vector rejection" before, neither in English nor in Russian.
Is there an established Russian term for it?
