A vector `vecA` ur is rotated by a small angle `triangletheta` radian `(triangletheta ltl)` to get a new vector `barB` In that case `|vecB-vecA|` is:

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

vecA + vecB = vecC . Vectors vecA and vecB if rotated by angle theta in the same sense to from vecA and vecB then (thetane0) :

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

The angle between the two vectors veca + vecb and veca-vecb is

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

Show that, in case of vector addition vecA+vecB=vecB+vecA

The angle between vectors (vecA xx vecB) and (vecB xx vecA) is :

The angle between vectors (vecA xx vecB) and (vecB xx vecA) is :

The angle between vectors (vecA xx vecB) and (vecB xx vecA) is :

The resultant of two vectors vecA and vecb is perpendicular to the vector vecA and its magnitude is equal to half the magnitude of vector vecB . The angle between vecA and vecB is
