I tried the emulator, and it appears to work fine with the CAS definition of the series in the function app. The only problem I can see is that the slope does not get computed (returns NaN - - not a number). Other features work as expected, e.g., root, or area between two x values.

Well, then it doesn't make sense at all
I'm lost with your issue... are you sure you copied the whole formula without any "spelling" mistake while removing the end of the formula? I remember I copied it once with an error and it couldn't calculate but wouldn't return any specific error message.
