Wolfram|Alpha is described as is a ‘computational knowl
edge engine’

by its
developer
Wolfram Research,
and
can be accessed from
http://www.wolframalpha.com/

.
It is a free web based application
that enables the
user to compute or search, u
sing a single line entry format.
It can be accessed from
tablets, mobile phones and the like.
Unlike
Google

it does not produce
a list of
links
to other websites and the like which refer to the content of a quer
y, but either carries
out a requested computation or provides factual information from its data base in
relation to the content of
the query
.


Entries/queries

can be fairly ‘free
-
form’ in
combination of

words and
/or

mathematical symbols.

The following is

an example of
a computation request
:


Part of t
he response to this request is:



Functions can be fitted to data
. Entering ‘linear fit {{1,2}, {4,6}, {8,5}, {11,7}}’
results in the following:


T
ry other
modelling
functions, or
even
not specifying a
function type at all
.

For teachers and students
Wolfram|Alpha can be used as a
n accessible and flexible
tool for mathematical

computations, or for finding information about mathematical
topics
.

The following is
a response to ‘icosahedron’
:





Interest
ing three dimensio
nal images of shapes such as a K
lein bottle can also be
obtain
ed, for example via the entry ‘k
lein bottle’:



Queries can also be numerical, for example, ‘first fifty primes’:


Interestingly, you will notice there are less than fifty
primes

listed
. You do, however,
have t
he option of seeing the rest (
More
).

Try modifying the

query to ‘prime’
(and
explore the different sense of meaning)
or ‘Australian prime minister’
.
There are
many
other
possibilities,
