TSIMP
VER
14-70
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
⎛
-------------------------------------------------- -
TSIMP
⎝
SIN 5X
gives:
4
EXP i x ⋅ ( )
+ 1
------------------------------------- -
2
EXP i x ⋅ ( )
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).
