To be of unit length
Vector quantities have a direction and a magnitude. However, sometimes one is interested in only the direction of the vector and not the magnitude. In such cases, for convenience, vectors are often "normalized" to be of unit length.
I read the above at brilliant.org
Vectors are often normalized: passive part object plus to be plus past participle
Why do we need "to be" here and what does the whole phrase "to be of unit length" describe or modify here?
