Graphing Aids:
A graphing calculator is any handheld device that allows the user to input equations in “y=” form and will output an image of the graph for that input.

CASs:
Software run on a computer that allows the user to input equations and will provide a graphical image for that input. 

Fixed Window:
Plotting graphs using a pre-selected range of x and y values.

Automatic Window:
Plotting graphs using a pre-selected range of x values where the ranges of y values are calculated such that al points fit in the window.

Graphing utilities allow for the user to graph equations that would be otherwise difficult to graph with pencil and paper. The user of a graphing calculator can approximate values of mathematical problems that are not exact values.

The common miscellaneous ways that using a calculator or other graphing utilities makes calculations easier is mentioned in this tutorial. These mathematical tools can give inaccurate results if they are used improperly. It is good to understand them to prevent from doing them when using graphing utilities.
