The plotting capabilities of symbolic algebra systems are among their most powerful features. With Scientific Notebook you can carry out operations interactively. You can plot functions and expressions; examine the results; revise the plot and examine the results of the revision; add multiple functions to the plot; and carry out a variety of other plotting procedures. This adds an experimental dimension to problem solving that was not easily accessible in the past. In the preceding chapter, several plots were provided to illustrate properties of functions. You will find yourself creating plots in many situations to help answer questions about the behavior of different functions or families of functions.
