Below is a brief overview of some of the features
available to users of Autograph

2D Graphing
Creation of interactive objects based on moveable
points.lines, vectors, conics, polynomials, shapes,
data sets.
Shapes and transformations
Shapes either from a set of points or from a list of
presets. Transformations including
stretches
shears
reflections
rotations
enlargements
translations
as well as arbitrary matrix transformations. Transformed
objects update as the original object changes and can
be chained. Rotations and enlargements can be animated,
changing the value of the parameter, as can matrix
transformations.
Vectors
Create as an interactive object using points or with
cartesian or polar coordinates. Vectors can be added,
subtracted, multiplied, duplicated, have the angle
between them found and can form the basis of straight
lines and translations.
Equations
One line true notation entry in explicit, implicit,
parametric, piecewise, and polar forms.
Slow plot allows you to draw curves incrementally, stopping at important points.
Calculus
Differentiate, find the area below a curve or between
two curves. Integration treated as a first order differential
equation.
Differential equations
First and second order solved. Plot slope field. Boundary conditions specified
interactively.
Numerical methods
Bisection solution. Newton Raphson method. Step forwards
and backwards.
Numerical integration.
Rectangle, trapesium and Simpson's methods. Animated the
number of divisions.
Tangents and normals
Plot tangents and normals to curves; evolute draws
these in many places along the curve, often leading
to striking shapes.
Scatter graphs
Data sets from points, files or entered through
Autograph's spreadsheet
Least squares regression graphically illustrated
Fit straight lines, polynomial or fit your own
equation to the data
Three dimensional graphing
Points as the basis of objects
Form objects including:
shapes
lines
vectors
planes
Shapes
Either form shapes from joined triangles or select
from a list of preset shapes
Transform shapes:
Rotations
Reflections
Enlargements
Translations
as well as arbitrary matrix transformations.
Lines and planes
Lines and planes from points, vectors or equations.
Intersection of:
Lines and planes
Two planes
Three planes
Vectors
Vectors created from points or entered in Cartesian
form. Add, subtract, copy, vector and scalar products.
Equations
Explicit, implicit, parametric, spherical and cylindrical
polars
Draw normals and tangets to surfaces and parametric curves Acceleration and velocity
vectors to parametric curves
Extra features for the
classroom
Customisability
Everything from the selection behaviour through the
backgrounds, behaviour of axes and thickness of the
lines to the layout of the toolbars
Interactive whiteboard friendly features
An on-screen keyboard allows you to enter equations
without returning to your computer.
The scribble tool lets you draw directly onto an Autograph page, avoiding the
layer system used by some manufacturers Many results are displayed in the status
bar; to make these more visible from a distance these can be duplicated in a
larger font in the status box. Whiteboard mode sets Autograph's preferences in
a way that is suitable for use with a data projector.
Instructions window
Leave instructions for pupils to follow embedded in
a saved Autograph file.
