The conversion from rectangular to polar and vise versa becomes really simple with the help of a little program that you assign to a key, I have it assigned to the |MODE| key. I'll explain the way a have it in my 50g, I'm assuming you are working in RPN with soft-menus.
The next program toggles from REC mode to CYLIN (or SPHER), since we are working in a plane is like toggling from RECTANGULAR to POLAR.
<<
IF -16 FC?C
THEN -16 SF
END
Press: 2 2 |ALPHA||ALPHA| A S N |ENTER|
Now every time you press |left-shift| |ALPHA| |MODE| the 50g change the mode, go ahead and try it, and look how in the top of the screen changes from XYZ to XLZ (L represents the angle symbol).
Now I'll show you how simple is the problem, Let's work with just four decimal places:
Press and hold |left-shift| and then press |MODE| now press |F1| to choose FMT then
press 4 and |F2| to choose FIX.
In the math menu let's choose vectors
Press |left-shift| |SYMB| then and |F1| to choose VECTR.
To convert from REC to POL make sure XYZ shows on top of the screen, if not press |left-shift| |ALPHA| |MODE| .
Lets say you want [3 4] in polar press 3 |space| 4 |F5| to choose ->V2
now toggle the mode |left-shift| |ALPHA| |MODE| , you should have the polar representation in the screen.
To convert from POL to REC make sure XLZ (or XLL)shows on top of the screen, if not press |left-shift| |ALPHA| |MODE| .
Lets say you want [5 L 60] (5 units and 60 degrees) in rectangular press 5 |space| 60 |F5| to choose ->V2
now toggle the mode |left-shift| |ALPHA| |MODE| .
The next program toggles from REC mode to CYLIN (or SPHER), since we are working in a plane is like toggling from RECTANGULAR to POLAR.
