If you are going to have any success at all with Mathematica, you should at a minimum go to the Help menu select Virtual Book and read the introductory material. You can access that by clicking on arrows to the left of headings in the window you see until you get to specific articles. The articles can be read by clicking on them which will open them in a separate window. One of the nice aspects of the Virtual Book is the windows that open are Mathematica notebooks which means you can execute any of the commands to get a result. Further, you can edit the parameters and re-execute the command to see how it changes the output. And since any changes you make to these documentation notebooks won't be saved, you can change things without fear of messing up the documentation.
