Let v be a nonzero vector. The angles , , between v and the unit vectors

Question:

Let v be a nonzero vector. The angles α, β, γ between v and the unit vectors i, j, k are called the direction angles of v (Figure 30). The cosines of these angles are called the direction cosines of v. Prove that

cos a + cos B+ cos y = 1
