HP48G Project: Introduction to the HP48G
Purpose:
To familiarize students with the matrix functions on the HP48G,
to introduce specialized software for the HP48G, and to use that
software to solve systems of linear equations.
Prerequisites:
Sections 1.1, 1.2
HP48G Commands Used:

1. Review your User’s Guide for information on entering matrices by using the command line and
by using the MatrixWriter feature.
2. You are required to submit a report for each project you do. This report should be a record
of your calculations, but should include more than just calculation. You should also include your
comments about your calculations. Also, if a question is posed in the project, you are expected to
answer it to the best of your ability, in complete sentences and with decent syntax. Failure to do so
will result in a loss of credit for that question.
3. Put your calculator in the
MTH
directory (if it isn’t there already). You should see a menu of
directories, including
VECTR
,
MATR
, and
LIST
. Press the
MATR
menu key to get into the
MATR
directory. You will again see a row of directories, including
MAKE
and
NORM
. Press
the
ROW
menu key to get into the
ROW
directory. Take note of the following menu keys:
RCI
,
RCIJ
, and
RSWP
. To see
RSWP
, you must press
NXT
. To return to the first page of the
ROW
menu, hit
NXT
again.
