|ES-40 Vector Resolution - Direction Cosines|
||A vector may also be specified by magnitude and the angle it makes with the three coordinate axes. This is indicated in the three figures we see here.|
|The components, Fx, Fy, and Fz may be determined.|
|A force in three dimensions may be specified by its magnitude and
either direction cosines,|
or Euler angles.
If a force is specified in Cartesian coordinates, it may be given as the magnitude of the components and unit direction vectors , , .
