The sum and product of the
values are calculated, both of these operations are commutative.
Due to the odd-even identities of trigonometric functions ,
.
Therefore, the order of the angles does not matter.
\For example, let two points be
and
.
Find the distance and interchange the points.
\
.
Where
and
.

Now interchange the points.
\Let two points be
and
. Where
and
.

Therefore, the order of the points used in the polar distance formula is not important.
