HP35s Entering complex number arguments

[Merwedv]

Hi Dieter,

Thanks so much for your response. It does seem very obvious now that you clarified. I was regarding "i" as a operand, rather than an actual number, albeit complex, and that completely threw me off the right track. (led astray by the xiy notation).

As for "r /_ theta", since it is merely a shorthand of r*e^(j*theta), it is neither an operand nor a "number"(like i) and cannot be treated as such. I spend some time learning how to program the thing (not as difficult as I anticipated), and did the following to be able to use the X and Y registers to enter a complex number in the r /_ theta notation:

Code:


A001 LBL A
A002 REGYxCOS(REGX)
A003 ixREGZxSIN(REGY)
A004 +
A005 RTN

So it will take the Y-reg as the magnitude, and the X-reg as the angle, and place the complex result in X-reg, in either rectangular or polar notaion, depending on the diplay mode.

Cheers,
Merwe
