Absolute Value of Complex Dot Product is Commutative/Examples/2+5i dot 3-i

Example of Use of Absolute Value of Complex Dot Product is Commutative

Example: $\size {\paren {2 + 5 i} \circ \paren {3 - i} }$

Let:

$z_1 = 2 + 5 i$

$z_2 = 3 - i$

Then:

$\size {z_1 \circ z_2} = 1$

Example: $\size {\paren {3 - i} \circ \paren {2 + 5 i} }$

Let:

$z_1 = 3 - i$

$z_2 = 2 + 5 i$

Then:

$\size {z_1 \circ z_2} = 1$

As can be seen:

$\size {\paren {2 + 5 i} \circ \paren {3 - i} } = \size {\paren {3 - i} \circ \paren {2 + 5 i} }$
