Drawing curves

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

Animated curves

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

• 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.
