If you are having trouble with the syntax of a certain command, you can
find basic help by typing "?" immediately followed by the command. This
will provide you with the basic syntax and function of the command. An
extended version of the "?" is the double "?". By placing two question
marks directly in front of the command in question, you can bring up the
basic command syntax and operation, plus all of the other options you can
use with the command.
If you type:
??Integrate
You will get the same information as "?Integrate", but will also
provide the option, "Attributes", and its syntax.
The single most useful upgrade from the previous versions of Mathematica
is the improved Help Browser. This will probably provide an answer to any
question you may have concerning the commands for Mathematica. The Help
Browser can be opened by clicking on the "help" button in the upper-right
corner of the window, then clicking on "help". The Browser will come up
in a separate window. Click on "Master Index" then type in the command
in the "Go To:" line. Click on the highlighted command in the right-most
box below the "Go To:" line. Now click on the blue underlined command in
the lower window. This will bring up detailed help about that command in
the lower window. If the command you are typing does not seem to exists
in the help browser, you can try to find it by clicking on the letter it
starts with, then scrolling through the list of commands that begin with
that letter.
Note: The command to differentiate a function is simply "D".
