Angle Between Two Vectors

The angle between two vector A and B is theta . Vector R is the resultant of the two vectors. If R makes an angle (theta)/(2) with A, then

Find the angle between two vector A=2hati+hatj-hatk andB=hati-hatk.

What is the angle between two vector forces of equal magnitude such that their resultant is one-third of either of the original forces?

For what angle between the two vectors, their resultant is maximum?

Angle between two lines in vector and cartesian form

The vector sum of two vectors vecA and vecB is maximum , then the angle theta between two vector is

The magnitude of the vector product of two vectors is sqrt(3) times their scalar product. The angle between the two vectors is
