About Vector formulas

Vector formulas contain the list of formulas to perform numerous arithmetic operations on the same vector, and between two vectors. These formulas help in performing many such operations systematically and easily.
The various formulas include the dot product, cross product, projection of vectors, direction ratios, direction cosines, the magnitude of a vector, unit vector etc. Get the List of all Maths formulas in one place.

Direction ratios of vector B =ai^+bj^+ck^ is a, b, and c respectively.

The direction cosine of vector B is the cosecant of the angle made by the vector with the x, y, z, axes respectively.
