An application to draw and animate functions and curves

Drawing curves

Drawing functions, parametric or polar curves, choosing color, thickness and zoom.

Drawing curves

Animated curves

Animating curves (translation, rotation, zoom, distortion) with persistence and colors gradient.

Animating curves

A dynamic algebra application to do calculations by steps and with explanations

  • Calculations by selection and move (a variant of the drag and drop adapted to touch use for tablets and smartphones) : you select an expression then you put the cursor where you want and ask for a "Move (Calculation)". EpsilonWriter proposes transformations when the situation allows them. The gestures are transformed to mathematical operations:
    • numerical calculations, expand and simplify,
    • factoring, simplification,
    • adding to the 2 members (substraction, multiplication, division), substitution.
  • Calculations on selection : you select an expression the you ask for a calculation. EpsilonWriter proposes an expression then you ask for a calculation. EpsilonWriter proposes calculations when the situation allows them :
    • Exact or approximate numerical calculations, expand and simplify,
    • Second and third degree equations solving schemes,
    • Transform some logical conditions to a domain or a set of solutions,
    • Limit calculation, derivative calculation,
    • Table of signs, Table of variations,
    • Formula generation,
    • Complex numbers calculations.

An application to run resources with :

When the student ask for questions checking, she get a score and an explanation.

The Aristod company, which developed these tools, ceased its activities in April 2019, due to the very low interest that these tools have generated.
Jean-Francois Nicaud, the main author of these tools, keeps them available to users on this website for a few years.
