If `veca and vecb` are unit vectors and `theta` is the angle between `veca and vecb`, then `sin.(theta)/(2)` is

If veca and vecb are unit vector and theta is the angle between then, then |(veca - vecb)/2| is:

If veca and vecb are unit vectors and theta is the angle between them then show that |veca-vecb|=2sin.(theta)/(2)

If veca and vecb are unit vectors then what is the angle between veca and vecb for sqrt(3)veca-vecb to be a unit vector?

If veca,vecb are unit vectors and theta be the angle between them show tat sin((theta)/(2)) = 1/2 |veca-vecb|

If veca,vecb are unit vectors and theta is the angle between them, show that sin""(theta)/(2)=(1)/(2)|veca-vecb|

Let veca and vecb be two unit vectors and theta is the angle between them. Then veca+vecb is a unit vector if :

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

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