Показать описание
In this video explaining scalar product vector. In the example first we calculate λ value then after solve vectors are perpendicular vectors. This example is very easy. When two vectors are perpendicular it means that they form a right angle (90 degrees or pi/2 radians) with each other. This also means that the dot product of the two vectors is equal to zero.
