Question
Resolve the rectangular components of a vector in three dimensions?
Solution
Let us resolve the rectangular components of a vector represented by
in three dimensions.
From point P, draw a perpendicular PM on XY plane and from M draw a perpendicular PM on XY plane and from M draw perpendicular ML on Y axis and MK on X axis. '
Using triangle law to
The above expression gives us the rectangular components of a vector in three dimension.
