Re: HP48GX units problem Message #3 Posted by Noël Cotter on 1 Aug 2007, 5:36 p.m., in response to message #1 by Noël Cotter
I see that the text was garbled when I posted it. I'll try editing it in and see if it will make more sense.
If on my HP48GX I do the following:
1000
Hz
1E-6
F
*
INV
I get:
1000_Ohm
(Ohm symbol does not post correctly)
Where as the correct answer is:
(0,-159.154943092)_Ohm
First, it's obvious the calculator has not made the conversion from Hz to radians/sec.
Next, if I type:
0,2)
Ohm
I get an error message, "Bad Argument Type", so apparently the units cannot be appended to a complex number. But 1 / (1 Hz * 1 F) does NOT equal 1 Ohm even if we neglect signs or complex numbers.
There, that makes a little more sense.
