Conjugation on the HP-35s



#2

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,

ENTER
ABS
x2
x<>y
/

will give its complex conjugate.

Karl,

Very nice. The best I had come up with so far was:

ENTER
ARG
->RAD
i2
*
ex
/
