50g

Hello
I am a new member to the HP 50G forum. Having received mine yesterday I 
have to say I am impressed.
I have finally conceded that my HP65 has died. I returned it to HP to 
see if they had an old working strip readers but to no avail. I have to 
thank HP for their efforts in trying to help.

My question is regarding complex numbers. I did buy the HP 35s and the 
33s but the problem with these calculators are that they will not 
handle square root or sqaure complex numbers.
Hence the venture into the HP 50G terrain.

This does do what I want my only question at this time is, Is there an 
easy way to switch from Polar to rectangular without having to go 
through the "Mode" then scroll down to select the options for 
rectangular or polar. I note you can press "Right shift CAT then select 
Cylin" I just wondered if there was a quicker way.

Any advice will be welcome.

You can also do what a I did, I assigned a little program to the [MODE] key that toggles between rectangular or polar, to do that:

- Enter this a program in the stack

«

IF -16 FC?C

THEN -16 SF

END

»

- Press 21 [ALPHA] [ALPHA] ASN [ENTER]

Is that simple! Now every time you want to switch form rectangular to polar or vice versa, just press [LEFT-SHIFT] [ALPHA] [MODE] in other words [LEFT-SHIFT] [ALPHA] is USER
