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

i.i=1

j.j=1

k.k=1

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

Today I will discuss about the cross product of unit vectors:

i x j = k

j x k=i

k x i =j

j x i= -k

k x j= -i

i x k= -j

and

i x i = j xj = k x k =0

Do you know how the above results come? If your answer is no, then let us discuss it: Continue reading “cross or vector product of unit vectors”
