HP 35s polar/rectangular conversion « Next Oldest | Next Newest »

 ▼ CD Dodds Junior Member Posts: 9 Threads: 3 Joined: Nov 2013 11-28-2013, 12:25 PM When you do rectangular/polar conversion you enter it as a complex number and change the display format according to what you want to see. Is there a way to separate the angle from the vector, or the "x" coordinate from the "y" coordinate? Like retrieving the fraction part or integer part from a number. ▼ Michael de Estrada Posting Freak Posts: 1,665 Threads: 142 Joined: Jan 2009 11-28-2013, 12:30 PM Buy a used 33s or 32SII. Problem solved. Dieter Senior Member Posts: 653 Threads: 26 Joined: Aug 2010 11-28-2013, 12:44 PM The 35s has no commands to split a complex number into its real and imaginary part. However, polar coordinates are easy: Convert (3; 4) to polar coordinates ``` 3 i 4 [DISPLAY] .0 => 5,0000 (theta) 53,1301 ``` or the other way (polar to rectangular) ``` 5 (theta) 53,1301 [DISPLAY] 9 => 3,0000 i 4,0000 ``` Both display options represent the same number. To obtain distance and angle (in either display mode): ``` [ABS] => 5,0000 ' distance LastX [ARG] => 53,1301 ' angle ``` Getting the rectangular coordinates 3 and 4 from this is a bit tricky, though. ;-) Dieter Edited: 28 Nov 2013, 12:50 p.m. ▼ CD Dodds Junior Member Posts: 9 Threads: 3 Joined: Nov 2013 11-28-2013, 01:56 PM I have a 32sII and it has always been one of my favorites. Have a 33s it works but never got attached to it. I am helping teach a "land surveyor in training" course at the annual state survey convention and we need to use calculators that are allowed on the Federal Land Surveyor in Training test. I do like the 35s and I like it even better now. Thank you Dieter for your help. It's much appreciated. Chad R.

Thanks Chad ▼ Dieter Senior Member Posts: 653 Threads: 26 Joined: Aug 2010 11-28-2013, 02:39 PM This kind of solution was discussed in detail as soon as the community realized that there are no traditional P<>R commands on the 35s. Some routines (that even preserve the stack) can be found in this discussion from 2007. A summary of all efforts, with optimized solutions, can be found in the articles section on this website. Here, even the state of flag 10 is preserved. Dieter
