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:

 

 

 

⎛SIN(3X) + SIN(7X)⎞

 

SIMP⎝--------------------------------------------------

SIN(5X)

⎠

 

gives:

 

 

 

EXP(i ⋅ x)4

+ 1

 

 

-------------------------------------

 

 

EXP(i ⋅ x)2

 

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).

14-70
