In this part of the tutorial, we will cover the user interface of Mathematica. When you first open Mathematica, you will hear a sound and you will see three windows: the navigation bar, the notebook, and the symbol pallet.

The navigation bar is across the top, and will say Mathematica 4.1 - [Untitled-1].

The notebook is the large white area. This is where you tell Mathematica what you want it to do and see the results.

The third window is a pallet of mathematical symbols, to allow you to enter formulas and the like. All of the symbols listed on the pallet are available as functions that you can type into the notebook, so unless you just want things to look prettier, you don't necessarily need to use it.

Instead of using the symbol , you can type Pi and Mathematica will know what you mean. Similarly, you can use I in place of , the imaginary part of complex numbers, and E in place of , the exponential. Later we will use Integrate to evaluate definite and indefinite integrals.
