Input: i=sqrt(-1); u:=(x*exp(i*y)*log(z)); df(u,x,1,y,2,z,1);
i*y
Output:
- e
--------z
• Integrate a function
Input: f:=x*exp(x); int(f,x);

For details on the syntax, supported operations, functions, packages, etc. of the i41CX+ CAS
please see the online REDUCE User’s Manual. Because the HP-41CX character set does not
include curly braces ("{" and "}"), these are substituted by square brackets ("[" and "]") in the
i41CX+ CAS for both input and output. However, the "{ } <-> [ ] Conversion" global option
can be used to automatically make this conversion when importing/exporting and when using
the I41CXED text editor. Enabling this option allows seamless compatibility between
REDUCE and the i41CX+ CAS.
The Financial Decisions Pac, Advantage Pac, and I41CX-MATH module are just three
examples of the powerful capabilities enabled by the use of expansion pacs. And there are
over 100 such expansion pacs available! The combination of i41CX+ and expansion modules
comprise a very powerful small package. Combined with programmability, there is virtually
no calculation application beyond the reach of i41CX+!
