WebThe direction cosines of the point P describe the angles between the position vector OP and the three axes. If P has coordinates (x,y,z) then the direction cosines are given by cosα = x p x2 +y2 +z2, cosβ = y p x2 +y2 +z2, cosγ = z p x2 +y2 +z2. Now we can find an interesting formula if we take the three direction cosines, square them, and ... WebGiven, vector A = 2i + 4j - 5k.
