yksikkövektorilla
Yksikkövektorilla is a Finnish term that translates to "with a unit vector" or "by a unit vector" in English. In mathematics and physics, a unit vector is a vector of length one. Unit vectors are often used to indicate direction without regard to magnitude. They are frequently denoted by a hat symbol (^) above the letter representing the vector, such as $\hat{u}$.
When calculations involve a "yksikkövektorilla", it implies that a unit vector is being used as a multiplier
