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.

The use of graphing utilities can facilitated the visual representation of mathematical equations that are otherwise very difficult to graph by pencil and paper. Graphing calculators also allow the user to approximate values of problems that are not exact values.

Common miscellaneous ways that using a graphing calculator or CAS will make the calculation work easier is discussed in this tutorial. Mistakes that are made by CAS and calculator users are important to be aware when working with these mathematical tools.
