Question
The projections of a vector on the three coordinate axis are 6, - 3, 2 respectively. The direction cosines of the vector are
Options
A.6, - 3, 2
B.
C.
D.
Solution
Projection of a vector on coordinate axis are x2 - x1, x2 - y1, z2 - z1
x2 - x1 = 6, y2 - y1 = - 3, z2 - z1 = 2
The D.C′s of the vector are
x2 - x1 = 6, y2 - y1 = - 3, z2 - z1 = 2
The D.C′s of the vector are
