Creation of interactive objects based on moveable
points.lines, vectors, conics, polynomials, shapes,
Shapes and transformations
Shapes either from a set of points or from a list of
presets. Transformations including
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
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.
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.
Differentiate, find the area below a curve or between
two curves. Integration treated as a first order differential
First and second order solved. Plot slope field. Boundary conditions specified
Bisection solution. Newton Raphson method. Step forwards
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.
Data sets from points, files or entered through
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:
Either form shapes from joined triangles or select
from a list of preset shapes
as well as arbitrary matrix transformations.
Lines and planes
Lines and planes from points, vectors or equations.
Lines and planes
Vectors created from points or entered in Cartesian
form. Add, subtract, copy, vector and scalar products.
Explicit, implicit, parametric, spherical and cylindrical
Draw normals and tangets to surfaces and parametric curves Acceleration and velocity
vectors to parametric curves
Extra features for the
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.
Leave instructions for pupils to follow embedded in
a saved Autograph file.
