HP 49g Graphing Calculator - Manual (Page 49)

You can display a list of flags by pressing
flags
when the Calculator
Modes input form is displayed. With the list displayed, you can set or clear
particular flags.
To set or clear a flag:
ill
02 Const-snt •+ 5yHt
03 Functiiin ■ * iyHb
iH PoyH«nt at «rid
15 -*V2 -*• Mictor
20 UndirFi.*>H •+ 0

1. Press ® or ® until the flag you want to
change is highlighted.
2. Press
CHK.
If the flag was set before, it is cleared; if
it was cleared before, it is now set. (The flag is set if it has a check
mark beside it.)
Algebraic and RPN modes
The HP 49G provides two modes for interpreting and displaying
calculations: algebraic and RPN.
Algebraic mode
Algebraic mode is the default mode. In this mode, you perform
calculations by entering the arguments
after
the command (which, in
most cases, means entering numbers, fvmctions, and operators in the
same order that you would write down tire expression on paper). For
example, to find sin(30) in algebraic mode, you enter the command—
(SIN) —and then the argument: 30.
You enter the command and its arguments on the command line and:
• press to obtain the result in exact mode, or
® press 0 0JM1 to obtain the result in approximate mode.
Exact mode and approximate modes are explained on page 2-22.
If a calculation yields a number of results, the results are displayed
together in a list: ¡resulti, result 2, resultg, ...}.
In algebraic mode, previous calculations are
retained in history together with their
results. Each calculation is displayed at the
left of the screen, and the corresponding
result is displayed on the next line at the
right of the screen (as in the example on the
right).
