HP Prime will not calculate slope in graphing from function defined by program
05182020 11:22 AM
My Prime calculates correctly, on the graphing page, the slope of a graphed function whose formula is typed into the Symb page. It will also graph from a function defined in the Program section, and even calculate the area under the graph. However, it will not return a value for the slope of such a function (graph), or solve for a root or extremum (for programs of more than one line), even though those operations work correctly for functions defined by formulas typed into Symb. Is there a way around this? If not, does anyone understand why it works this way?

Example?
How would the derivative or integral of your "program" be found?
Although I work for the HP calculator group as a head developer of the HP Prime, the views and opinions I post here are my own.

Tim Wessman,
I graph a function defined in a program in the same way I graph a function whose formula is typed into Symb in the Prime except that instead of putting the formula, such as "x^21", into Symb, I put in the program name, such as "FLTR(X)" (with "X" as the variable name), which program has been defined in the Program section of the Prime. Then, I find the derivative at a point or the integral between specified limits of FLTR(X) in the same way I would for the typedin function X^21, except that it works for the integral, but doesn't for the derivative (if the programs has more than one line).
