RE: (Bug?) HP48 Equation Library
My personal preference is the piecewise function. It's a more succinct representation of the math involved, and also points out the importance of the relative values of x, a and c. This is JMHO though, so there may be very good reasons to do it the other way.
Perhaps a decision tree keyed to these relative values could be used to select the equation (of the 4 listed at the bottom) that is presented to the solver. You'd have to have some error handling if, for example, the user asked for a solution for P when no value for a was entered, but I'm not telling you anything new. |
