Determine or find out the direction cosines and direction angles for a = (2, 1, -4)
Solution
We will require the magnitude of the vector.
||a|| = √ (4+1+16) = √ (21)
After that the direction cosines and angles are,
cos α = 2/√21 α = 1.119 radians = 64.123 degrees
cos β = 1/√21 β = 1.351 radians = 77.396 degrees
cos γ = -4/√21 γ = 2.632 radians = 150.794 degrees
