Last time I have written about the properties of unit vectors that is:

Dot product of unit vectors :

i.i=1

j.j=1

k.k=1

i.j=j.k=k.i=0

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”
