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.
