Theory. Direction cosines of a vector
We label these direction angles alpha α - angle with the x axis, beta β - angle with the y axis and gamma γ - angle with the z axis.
To find the direction cosines of the vector a is need to divided the corresponding coordinate of vector by the length of the vector:
|cos α =||ax||;||cos β =||ay||;||cos γ =||az|
