Let be the unit vector in the direction parallel to the plane and let
be the component of F in the direction of
and
be the component normal to
.
Since,
Therefore,
From figure,
We know that the direction of is opposite of the direction of
, so we have
The unit vector in the direction normal to the plane, has components :
Therefore,
From figure,
∴
