Scalar resolute
From Wikipedia, the free encyclopedia
The scalar resolute (also known as the scalar projection) of a vector in the direction of a vector
(also "
on
"), is given by:
where θ is the angle between the vectors and
and
is the unit vector in the direction of
.
The scalar resolute is a scalar, and is the length of the orthogonal projection of the vector onto the vector
.
Multiplying the scalar resolute by converts it into the vector resolute, a vector.
