1.      Stages use the calculator as a tool.

The first stage is the stage of understanding about the significance of the calculator the graph. The essence of the understanding process is explained in basic and detailed on the graphing calculator.

The second stage is the stage of understanding the theory and use of calculator graphs in equations and inequalities to solve problems. Process the second is focused on how students understand the command, symbolic manipulation, and graphs to solve problems and equations inequalities with graphing calculator.

The third stage, namely stage of entering data about the calculator the graph. The process of entering data into the calculator about the process moving the language into the language of mathematics in the matter of the graphing calculator.

The fourth stage is the stage interpretation of the graphing calculator screen and draw conclusions.

2.      Use of graphing calculator.

From research conducted, noting there are many aspects use of graphing calculators in learning mathematics as the following:

a.       Graphing calculator is useful to determine and match
graphic images.

b.      Graphing calculator is useful to determine and match answer set of completion.

c.       Graphing calculator to give you real experience of graphic images.

d.      Settlement about equations and inequalities can be using the command, symbolic manipulation and graphics.

e.       Graphing calculator is useful to provide answers previously calculated without a calculator and speed up the completion mathematic matter.

f.       The constraints experienced by students in using the calculator graph is a paraphrase sentence into the language of mathematics calculator and disclose any appearance of the calculator screen to in math sentences.

g.      With the graphing calculator in the learning process mathematics math lesson more interesting and solving math problems easier.

h.      If the use of graphing calculators without the ability to offset understand the operating procedures and to think mathematically, it can because high levels of dependency, loss of confidence, and lazy thinking.
