Let be three vectors of equal magnitude such that the angle between each pair is If
If , then the value of is equal to
Angle between vectors are unit vectors satisfying
The values of ‘a’ for which the points A, B, C with position vectors respectively are the vertices of a right angled triangle with C = π/2 are
The vectors are the adjacent sides of a parallelogram. Then, the acute angle between its diagonals is
If are two vectors such that then angle between
The values of x for which the angle between the vectors is acute, and the angle between the vector and the axis of ordinates is obtuse, are
