To Karl Schneider, about 15c solver Message #1 Posted by R Lion on 25 Feb 2004, 9:50 a.m.
Near a year ago, I wrote:
In this MoHPC, you can read the next in the 32S page:
<<The HP32S featured to the first RPN solver. The HP34C had introduced the first builtin rootfinder which could solve for f(x) = 0 expressed as an RPN program. To use the root finder the user wrote a function that accepted x, and left f(x) in the X register. The RPN Solver on the HP32S allowed the user to enter a program which accepted multiple variables and computed f(a, b, c, ...) = 0. After entering a single program, the user could solve for any variable.>>
So, solve for ANY variable, is "the new" of the 32S/32SII/42S solver when comparing to the 34/15C solver.
I don't know if this is well known for the 15C users, but take a look at this post of Karl Schneider
Then you, Karl, promised an ARTICLE about this, do you remember? ;)
