|Conjugation on the HP-35s|
Message #1 Posted by Karl Schneider on 11 Aug 2007, 5:27 a.m.
As many of us know, the HP-35s offers easy entry of new complex numbers from the keyboard, but is missing basic functionality for manipulating or dissassembling complex numbers, or for assembling them from previously-obtained values.
Here's a reasonable workaround for the complex-conjugate function (i.e., negation of the imaginary component):
The product of a complex number and its conjugate is its magnitude squared,
ZZ* = |Z|2
So, Z* = |Z|2 / Z
With a complex number in the x-register,
will give its complex conjugate.
