Vector's directional cosines are called the cosines of the angles between given vector and the axes of coordinates:

vector's directional cosines

From the elementary geometrical considerations follows:

formulas to calculate directional cosines

, where aax,ay,az and aax2ay2az2

Besides, from the formulas above follows the relation:

cos 2 α + cos 2 β + cos 2 γ = 1
