As can be seen from the above figure,
For a given vector u =
→The x-component of u has the projection on the positive x-axis.
Therefore a is positive.
→The y-component of u has the projection on the positive y-axis.
Therefore b is also positive.
→For a given vector v =
→The x-component of v has the projection on the positive x-axis.
Therefore p is positive.
→The y-component of v has the projection on the negative y-axis.
Therefore q is negative.
