HP Prime Code Snippets and Relative Help for Carbajo's Xcas YouTube Videos

[lschroeder1947]

In this this thread we show how Jose Luis Tabara Carbajo in his Xcas YouTube Videos used 1 or 2 global CAS Variables as the parameters of a CAS View command line function with the result being returned to the History area.

In this thread posts, we include HP Prime CAS screenshots of the Xcas implementation found in his videos plus English comment of HP Prime CAS screenshots according to the Creative Commons Attribution license (reuse allowed) comment found in each video.

Due the usefulness of HP Prime screenshots to members becoming familiar with the HP Prime we will include all the HP Prime screens shots we made for the Xcas videos rather than only showing screen shots using 1 or 2 global CAS Variables as the parameters of a CAS view command line function.

We like using Entry set to Textbook except where noted. If we find the commands in the CAS menu, Math menu, or template keys we use them. Otherwise we look them up in the Catlg menu. If needed, we used the HP Prime Help key to assist with HP Prime CAS view entry.

The Xcas videos used uppercase letters A-Z for variables names. Since the HP Prime uses uppercase letters A-Z for Real, we changed variable names to lowercase. Lowercase made variable entry easier, since default mode for HP Prime CAS view is lowercase. The Xcas videos use Algebraic Entry thus all functions are written as lowercase. The HP Prime CAS view command line uses lowercase when a function name is displayed but displays some of the function results in the History area using uppercase.
