If `veca` and `vecb` are two vectors and angle between `veca` and `vecb` is `theta,` then

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

If veca and vecb are two unit vectors and the angle between them is 60^(@) then ((1+veca.vecb))/((1-veca.vecb)) 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 vector and theta is the angle between then, then |(veca - vecb)/2| is:

If veca and vecb are two unit vectors such that veca+vecb is also a unit vector, then find the angle between vectors veca and vecb .

If veca and vecb are two unit vectors such that veca+vecb is also a unit vector, then find the angle between veca and vecb .

If veca and vecb are two vectors of magnitude 2 and inclined at an angle 60^(@) then the angle between veca and veca+vecb is

If veca and vecb are two vectors such that |veca xx vecb|= veca.vecb , then what is the angle between veca and vecb ?
