Functions in the Arithmetic menu | HP 49g guide

These functions allow to simplify expressions by replacing some category of trigonometric functions for another one. For example, the function ACOS2S allows to replace the function arccosine (acos(x)) with its expression in terms of arcsine (asin(x)).

Description of these commands and examples of their applications are available in the calculator’s help facility (IL@HELP). The user is invited to explore this facility to find information on the commands in the TRIG menu.

Functions in the ARITHMETIC menu

The ARITHMETIC menu is triggered through the keystroke combination „Þ(associated with the 1key). With system flag 117 set to CHOOSE boxes, „Þshows the following menu:

Out of this menu list, options 5 through 9 (DIVIS, FACTORS, LGCD, PROPFRAC, SIMP2) correspond to common functions that apply to integer numbers or to polynomials. The remaining options (1. INTEGER, 2. POLYNOMIAL, 3. MODULO, and 4. PERMUTATION) are actually sub- menus of functions that apply to specific mathematical objects. When system flag 117 is set to SOFT menus, the ARITHMETIC menu („Þ) produces:

Following, we present the help facility entries for functions FACTORS and SIMP2 in the ARITHMETIC menu:
