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 HP-35s 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?

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.

UPDATE: I've been running through the Polar-to-Rectangular 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) Edited: 7 Apr 2012, 11:41 p.m.
