thoughts about HP35S P<>R  Matt Agajanian  04072012 Hello all, Yes, yes. I have used the P<R conversion routines here in the Software Library. Although, it's exactly how HP made it before. But, what are your impressions of the following method: for rectangular to polar: x [i] y [ENTER^] [ARG] ==> angle [x<>y] [ABS] ==> r I just haven't figured out the polar to rectangular process as I get stuck from that mousetrap of the HP35s inability to decompose complex numbers. Any ideas? !!I think I might've figured it out!! r [theta] theta [ENTER^] [ENTER^] [ABS] [LASTx] [ARG] [COS] [*] [ ==> X coord [x<>y] [ABS] [LASTx] [ARG] [SIN] [*] [ ==> Y coord So, what do you think?

Re: thoughts about HP35S P<>R  Michael de Estrada  04072012 1) Throw the 35S in the trash
2) Buy a 33S or use your 32SII
Re: thoughts about HP35S P<>R  Matt Agajanian  04072012 Well, it was a good challenge and yes, I'll admit, like I've said before, HP did drop the ball on the 35S. UPDATE: I've been running through the PolartoRectangular steps I've devised and it does indeed decompose a complex number! Here's the algorithm again: For Polar to Rectangular Conversions AND to decompose a complex number: (if Complex number is in display, omit this step) r [theta] theta [ENTER] Otherwise proceed from here: [ENTER] [ABS] [LASTx] [ARG] [SIN] [*] ==> Y coord (or imaginary component) [x<>y] [ABS [LASTx] [ARG] [COS] [*] ==> X coord (or real component)

Re: thoughts about HP35S P<>R  Nick R  04072012 I got so fed up with the 35S and its shortcomings that I returned it. Whoever designed it seemed to think units conversion was more important than coordinate conversions. I knew if I kept it any longer it would end up underneath a large hammer.
