Functions:

  • Numerical and algebraic calculation:
  • Calculation of fractions with a "one-touch" conversion between fractional and decimal display
  • Access to all mathematical functions such as vx, xy, log x, ex, etc. using the virtual keyboard for numerical and algebraic calculations
  • Calculates in degree and radian measure
  • Algebraic calculation with commands such as factor, expand, simplify, approx, combine, collect, etc.
  • Calculates with complex numbers
  • converts between sexagesimal and decimal
  • Random number generator, permutation, combinational logic
  • Vector calculation: calculates the scalar and cross product
  • Matrices calculation: creates matrices in a mathematical representation, adds rows and/or columns, determinants, transposition, eigenvector, eigenvalue
  • E-activities:
  • E-activities can be used by the teacher as a documentation tool for electronic examples and practical problems with accompanying text, mathematical formulae, 2D and 3D graphics, geometric drawing, dynamic geometry operations and tables.
  • E-activities can also operate and be used as a "workbook" for students, so they can investigate problems and document their learning successes, or to solve problems using instructions or by entering notes and then to store their work in a file.
  • E-activities thus bring together lines of text and calculations, dynamic geometry operation and all application menus like a written task in a standard textbook: descriptive text, using all applications by adding labelled "link strips" and dynamic geometry operations and additional note functions.
