Mathematica Primer
Mathematica is an extremely powerful software package that can numerically and
symbolically
manipulate all kinds of mathematical expressions involving algebra, series,
calculus, differential equations, matrices….the list goes on and on and on. Simply put,
Mathematica
can
do
(or
be
programmed
to
do)
just
about
anything
involving
mathematics and finds wide application in many branches of science and engineering.
Some important things to know before you start
:
•
Mathematica likes to do things symbolically…this way, virtually any expression or
task can be used as an
operator
or function to do something to something else (i.e.,
numbers, variables, expressions, lists, matrices, etc.)
•
Input syntax is CASE sensitive and
inflexible
: you must enter functions, arguments,
etc. correctly.
•
All functions (builtin or userdefined) are represented with brackets: [ ]
•
Builtin functions start with CAPITALS:
Sin[x], Cos[x], Exp[x], D[x], Integrate[x]
•
Use
Shift+Enter
to evaluate an input cell.
•
Mathematica puts the result of an input cell evaluation into a temporary global
