Hi all.

Please take a look at this complex number:

[tex]

\widehat C = \frac{1-\widehat a}{1+\widehat a}\widehat B,

[/tex]

where a hat indicates that the number is complex. Can you confirm me in that the length (modulus) of this complex number [itex]|\widehat C|[/itex] is given by:

[tex]

|\widehat C| = \frac{|1-\widehat a|}{|1+\widehat a|}|\widehat B|

[/tex]

Thanks in advance.

Best regards,

Niles.
