A Simple Mathematica Session


------------------------------------------------------------------------------------
Mathematica understands the usual operators + - * and ^.

The following session illustrates some of these features:

------------------------------------------------------------------------------------------
It also understands basic constants Pi and E.  It also knows
about a large number of mathematical functions such as Exp[x],
Sin[x], Cos[x], ArcSin[x], Log[x]

Note: (  all Mathematica Commands start with capital letter
              and  use only square brackets [ ]    )

The basic plotting command is Plot[f, {x, xmin, xmax}]
which plots the function f(x) from xmin to xmax
For example,

--------------------------------------------------------------------------------------
Here we find the derivative with respect to y
--------------------------------------------------------------------------------------

This gives the limit of the tangent function at Pi/2 approaching
from the right.

--------------------------------------------------------------------------------------
We do some factorizations
--------------------------------------------------------------------------------------

[Graphics:Images/htmlquickstart_gr_36.gif]
[Graphics:Images/htmlquickstart_gr_37.gif]

--------------------------------------------------------------------------------------
We solve an equation
--------------------------------------------------------------------------------------

--------------------------------------------------------------------------------------
We find the inverse function
--------------------------------------------------------------------------------------

There are many functions in Mathematica but it is often very
useful to be able to define functions oneself. This is illustrated
by the following example, which defines the function .
f(x) = x + x^2
