Re: HP17BII+ Questions - Got a Replacement and... Message #3 Posted by Eddie Shore on 9 Apr 2005, 12:55 a.m., in response to message #2 by VPN
I hate to say but Bob Wang was right! Using L() and G() does not return expected results.
For example,
L(A:LN(X+1))+Y÷G(A)
If I put X=3, then Y returns 0. (when it should return
-1.92)
If I put any number for Y, X returns SOLUTION NOT FOUND
(Example: if let Y=-5, I should get 8.35 for X)
Now for something really weird...
L(A:LN(X+1)+Y÷A
If I let X=3, then I get the Y=-1.92 result.
BUT If I try to solve for X, I get BAD GUESS; and if I try to solve for A, I get 0.
I am not sure if this is worth justifying replacing my old one and spending another $99.
