TSIMP Simplifies a given expression by rewriting it as a function
of complex exponentials, and then reducing the number
of variables (enabling complex mode in the process).
Example
Typing:
gives:
VER Returns the version number of your CAS.
Example
Typing:
VER
might give:
4.20050219
This particular result means that you have a version 4
CAS, dated 19 February 2005. Note that this is not the
same as VERSION (which returns the version of the
calculator’s ROM).
