Autograph

What is Autograph ?

Autograph is designed to help teachers and students visualize mathematics at the secondary/university level, using dynamically linked "objects."

1D Statistics and Probability

• Datasets and groupings
• Data entered as raw or grouped
• Continuous or discrete data
• Transform a dataset
• Dynamically change class width in grouped data

• Data representations
• Histograms including frequency density
• Cumulative Frequency Diagrams
• Box diagrams
• Portions of points
• Mean and three standard deviations
• Line chart
• Moving average
• Statistics box with set size, mean, standard deviation
• Table of statistics and tabulated values

• Operations with datasets

Measurements of histograms and cumulative frequency diagrams; Sample data sets, demonstrating the central limit theorem

• Probability distributions

Plot and sample:

• Rectangular (discrete or continuous)
• Binomial
• Fish
• Geometric
• Normal
• User-defined, continuous or discrete

2D Graphics

Creation of interactive objects based on moving points. Lines, vectors, conics, polynomials, shapes, datasets.

• Shapes and transformations

Shapes of a set of points or a list of presets. Transformations include:

• Stretches
• Scissors
• Reflections
• Rotations
• Magnifications
• Translations

• 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

A true line notation entry in explicit, implicit, parametric, part-and-polar shapes.

• Calculation

Differentiate, find the area below a curve or between two curves. Integration treated as a first-order differential equation.

• Numerical methods

Bissection solution; Newton Raphson method;  Go ahead and back off.

• Tangents and normal

Plot tangents and normals for curves; evolve by drawing this in many places along the curve, often leading to striking shapes.

• Scatter plots
• Point datasets, archived, or inserted into the Autograph spreadsheet
• Graph-illustrated least square stifiback
• Adjust straight, polynomical lines or adjust your own equation to the data

System Requirements

Autograph can be run on:

• Windows XP, Vista, W7, W8 and W10
• MAC OS (latest operating system supported)

For 3D pages, the graphics card and driver must support:

• Direct3D v9 or higher.
