14-70 Computer Algebra System (CAS)

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).
