Computer Assignment: Introduction to Mathematica
Purpose:
To provide a brief introduction to the
Mathematica
computing environment and to
use
Mathematica
to solve systems of linear equations.
Prerequisite Reading:
Section 1.1
Mathematica
Functions:
Clear, MatrixForm, Needs, ReplaceRow, Scale, Swap, TableForm.
Palette used in this assignment
: To use the following palette, click on the right cell bracket
containing the palette (or click anywhere inside the palette cell) and then choose
General
Palette from Selection
from the
File
menu to create a separate window containing the palette.
Drag the palette window to the far right side of the screen and resize the notebook window if

Mathematica
Arithmetic
Mathematica
can be thought of as a sophisticated calculator, able to perform exact as well as approxi-
mate arithmetic computations. As you read through this file, you will be asked to execute the contents
of input cells (shaded cells like the one immediately below this paragraph). As a first example, you will
add the fractions appearing in the following input cell. Using your mouse, click anywhere inside the
following shaded cell and then press
Shift+Enter
to perform the calculation (simply pressing
Enter
may be sufficient to perform the calculation on some machines).
A window will appear asking if you
would like to evaluate initialization cells contained in this notebook -
click
on
Yes.
(Initializa-
tion cells will be discussed at the end of this assignment.)
