Maths Translations
AVP Computing
COM 8
£24.50
This program deals with the translation
of triangles and quadrilaterals on a
progressive scale. There is a facility for
varying the speed of progress. It
explains how to move triangles and
quadrilaterals on a grid. Matrix
calculations are explained. At the end
of each section there are tests with a
revision if scores are not adequate. The
progressive nature of the program
makes it ideal for individual teaching
and revision, as well as for pupil use.
A suitable version is required when
it is to be installed on and executed
from a hard disc, or from Econet.

Angles and Trigonometry
AVP Computing
COM 39
£24.50
These programs are suitable for use by
teachers or students of mathematics or
physics.
Each of the programs presents
important principles and facts
concerning trigonometry. The
relationships between angles and their
trigonometrical functions can be
difficult to grasp by reading and the
study of static diagrams. These
programs present the facts through the
use of moving diagrams and graphs.
The intention is to aid the student to
understand the important concepts
involved in each case.
The programs provide the teacher
with an 'animated blackboard' as a very
clear way of introducing or illustrating
the topic. For example, graphs are
quickly produced which are of the
correct shape and have more impact
than freehand drawings. The programs
are a means of displaying changing
quantities in a convenient and clear
way and the fact that the model
responds to the learner's input, allow
him to test his own understanding and
makes it an efficient learning aid. The
programs are also suitable as a revision
aid to the topics.
A suitable version is required if this
is to be installed on and executed from
a hard disc, or from Econet.

Transformations
AVP Computing
COM 136
£24.50
This is a package which investigates
combinations of the simple
transformations, rotation,
enlargement, reflection, translation
and shear with an animated display of
up to five successive transformations,
which may be replayed as often as you
wish. The object to be transformed
may be a standard triangle or a simple
figure that you input yourself, on the
same disc, graph allows up to three
graphs to be drawn in different colours
using the input of functions in
algebraic form rather than in computer
form and a variety of trig functions
using single-key entry.
A suitable version is required if this
is to be installed on and executed from
a hard disc, or from Econet.

A -level Maths with Statistics
AVP Computing
COM 137
£24.50
A package of programs designed for
students working towards the
combined A-level in most syllabuses.
Graph allows up to three graphs to
be displayed at any one time. Input is
in algebraic form, with single-key entry
for a variety of functions. Angles can
be in degrees or radians, and
combinations of previous graphs can be
simple entered. Dy/dx builds up
families of solutions of differential
equations of the form dy/dx f (x.y)
with the user specifying a starting point
and an incremental step along the
tangent.
Samples introduces the student to
random sampling and the Central
Limit Theorem for means and
proportions from a population of
names. Either the sample or histogram
is displayed.
Binomial demonstrates the
relationship between the Binomial,
Normal and Poisson distributions.
Scatter allows entry of a scatter
diagram, and takes the student through
the steps of drawing two regression
lines using ideas related to Kendall's
rank correlation coefficient.
A special version is required when it
is to be installed on and executed from
a hard disc, or from Econet.

A-Level Matrices
AVP Computing
COM 141
£24.50
This disc covers the principal matrix
topics needed for A-level, especially
planes and the solution of 3 x 3
equations, matric inversion and
determinants.
The first program gives practical
examples of sketching planes and the
next illustrates the intersection of three
planes and their various possible
configurations. This ends with a test.
Another program shows graphically
the principal transformations of the
unit cube, especially squashing
transformations. Row operations are
considered in detail and users are then
invited to solve equations and invert
matrices by entering matrix elements
on the screen.
Help is given when needed.
The programs are written for Alevel
candidates either with one
computer in classroom or with access to
a network.
A suitable version is required also
when it is to be installed on and
executed from Econet.

The Puzzle Palace
AVP Computing
COM 194
£24.50
Trapped in the Puzzle Palace on a cold
and windy night, you make a desperate
bid to escape through the creaking old
door. However, this adventure is not
for the rash or impulsive thinker. It
demands all the pupils' problemsolving
strategies in order to make their
escape.
Throughout the adventure, many
varied mathematical activites are
encountered, their solutions necessary
to collect objects essential to complete
the journey.
Decision-making, record-keeping,
logic and map-making skills are fully
encouraged. This program is designed
to be used by small groups of
adventurers, and to encourage rich
mathematical discussion. It captures
the pupils' interest by its colourful
presentation and challenging
situations, is mathematically
demanding, but compulsive and fun.
Suitable for 9 to 13 year olds.
A suitable version is required if this
is to be installed on and executed from
a hard disc, or from Econet.
