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.

Sometimes in a Calculus course it is helpful to use graphing utilities to graph difficult functions such as the ones with repeating values. Graphing calculators are needed to approximate solutions to some Calculus problems such as Taylor approximation.

Using graphing calculators and mathematical software such as MAPLE, Mathematica and FORTRAN are used in a typical Calculus course to handle long calculations and graphs of difficult areas and volumes. The use of mathematical software creates a degree of error on some calculation. The bound of an error in approximating Taylor polynomials will be discussed in more detail later on.
