 Questions RE HP49G+ and HP17BII+Message #1 Posted by Eddie Shore on 13 Feb 2004, 12:26 a.m. HP49G+: Is there a way where I can bring up Numeric Solver App with a program command? It is for a business program/library I'm doing for the 49G+. HP17BII+: Is this worth the \$90 (to add to my collection)? I've read some positive and not so positive reviews on it. Thanks in advance, Eddie

 Re: Questions RE HP49G+ and HP17BII+Message #2 Posted by Francesc Casanellas on 13 Feb 2004, 6:06 a.m.,in response to message #1 by Eddie Shore I do not know if I understand well your question about the HP49G+ but here is one answer: Write your equation. Then write << 'EQ' STO 30 MENU>> The soft keys of the solver menu will appear. Examples: 1. simple equation (capacitor discharge): << 't/RC=LN(V1/V2)' 'EQ' STO 30 MENU >> 2. Two equations (use "next" soft key to see the other): << { 'I=Vs*(1-EXP(-t*R/L)/R' 't/RC=LN(V1/V2)' } 'EQ' STO 30 MENU >> 3. Put the variables in the soft keys in the order you want (voltage divider): << { 'V1/(R1+R2)=V2/R2' } {V1 V2 R1 R2} 'EQ' STO 30 MENU >>

Out of curiousity (sp?), Can I envoke the Numeric Solver screen, like the screen you get when launch the Finance Solver? Example: SOLVER A: B: C: EDIT CHOOSE ____ VARS ___ SOLVE

It is not easy to use and the infect HP manuals do not help. Refer to the HP 48G Advanced User's Guide or to "Programming in User RPL" of E.M. Kalinowski, available in www.hpcalc.org
