(Bug?) HP48 Equation Library

[Han]

Thank you all -- Brad Barton, SlideRule, and rprosperi -- for your insights. It has helped me understand the formulas much better. So from what I gathered,
\[ \text{if} \quad \quad f(x) = \begin{cases}
P\cdot (x-a), & x \le a \\
0, & x>a
\end{cases}
\quad \quad \text{and} \quad \quad
g(x) = \begin{cases}
M, & x\le c\\
0, & x> c
\end{cases} \quad \quad \text{then}\quad \quad
Mx = f(x) + g(x) -
\frac{w}{2}\cdot (L^2-2\cdot L \cdot x + x^2)
\]
So \( c \) is indeed hidden in the equation that shown in the AUR and in the display of the equation within the Equation Library.

I was trying to put together a list of formulas for a current project of mine, but it looks like it will be more than just copying and pasting the formulas from the AUR. I guess I will have to either learn or brush up on a lot of topics before this project is complete.

Again, thank you all for your insights and patience.
