I have been playing around with an HP 50g and I can't seem to get the mslv to work in RPN. I am using the example from the small guide that comes with the calc.
The equation is
[Sin(x)+ y,x+ Sin(y)=1]
[x,y]
[0,0]
I have tried using the small tic marks and not using them. It works fine if you switch to alg mode. Can someone tell me what I am doing wrong?
Thanks
If you key it in in RPN mode like this
['Sin(x)+ y','x+ Sin(y)=1'] ENTER
['x','y'] ENTER
[0,0]
and now invoke MSLV by [RS][NUM.SLV][6], you'll get
[.510973429389 -.489026570612] in level 1 of the stack. <---- BEWARE! Incorrect answer. See below ;-)
Note that the equations as well as x and y are in ' ' while keying them in, but as soon as you press ENTER after every line, the ' ' will vanish from the display.

No comma is needed in RPN mode
You commanists scare me!I get a liberal answer:
[1.82384112611 -.968154636174]What do you demonicrats say to that?
Any rebellous, imperialistic, or old republic answers?

V-PN McCarthy ;-) is right of course. I get this answer now, too. I don't know how I came upon my first answer and can't even reproduce it now.
EDIT: I know now what I did: I produced the first result using my 50G emulator, so I could retrieve it easily. I keyed in 'x+sin(x)=1' for the second equation. Should have double checked the result...AAARRRGGHHH!
Concerning the commas in RPN: do they hurt in any way other then being more work to do?
