If the angle between two vectors `vecA and vecB " is " 90^(@)` then

If the angle between two vector veca and vecb is zero then

The angle between vector (vecA) and (vecA-vecB) is :

If theta is the angle between any two vectors veca and vecb , then |veca.vecb|=|veca xx vecb| when theta is equal to

the angle between vectors veca × vecb and vecb × veca is

If veca.vecb=0 then angle between vector veca and vecb is:

Find the angle between the two vectors veca and vecb such that |veca|=1,|vecb|=1 and veca.vecb=1

Find the angle between two vectors veca and vecb such that : |veca|=sqrt3,|vecb|=2 and veca*vecb=sqrt6 .
