Let `bara` and `barb` be two unit vectors, and `alpha` be the angle between them.
Then `bara + barb` is a unit vector, if `alpha=`

If bara and barb are two unit vectors and theta is the angle between them , then the unit vector along the angular bisector of bara and barb will be given by

If bara,barb" and "bara-barb are unit vectors, then what is the angle between bara" and "barb ?

If bara and barb are unit vectors and theta is the angle between them, show that frac(1)(2)[bara-barb] = sin frac(theta)(2)

If baru and barv are unit vectors at an angle alpha and bara unit vector bisecting the angle between them, then bara=

If bara and barb are unit vectors, then the vector ( bara + barb) xx ( bara xx barb) is parallel to the vector

If bara and barb are unit vectors, then the max imum value of abs( bara + barb) + abs(bara - barb) is

If bara and barb are any two non-zero vectors, then find the angle between the vectors absbarb bara+absbara barb = absbarb bara-absbara barb

Let bara be a unit vector perpendicular to unit vectors barb and barc inclined at an angle a. then barb times barc is
