Last time I have written about the properties of unit vectors that is:
Dot product of unit vectors :
Do you know how the above results come? If your answer is no, then let us discuss it:
I have already explained in my earlier articles that dot product or scalar product between two vectors A and B is given as:
A.B = AB cos θ
where θ is the angle between A and B. A and B are magnitudes of A and B.
As i the unit vector along x axis Continue reading “dot or scalar product of two unit vectors”
