Daniel Marquès Technological Director Maths for More WIRIS CAS University

WIRIS CAS version adequate to the University education –First year in Calculus and Linear Algebra Currently used at –Open University of Catalonia –Technical University of Catalonia –Universidad Complutense de Madrid

Not so strange Originally WIRIS a University oriented software Most algorithms needed at University level are used at Secondary Education –Often it is only a matter of the input size or complexity.

We keep the same principle: Make it as easy as possible for students and teachers.

Specific features 1/5 In general, solve the same kind of problems, but more difficult –Because the input is greater or more complex (dimension, degree, number of variables, parameters, complex numbers,...)

Specific features 2/5 3D geometry and representation –Linear geometry and representation –Surface and curves plot

Specific features 3/5 Algebra of polynomials –gcd, lcm of univariate and multivariate polynomials –multivariate rational functions –New functions Resultants, Square Free decomposition, Groebner basis, complex roots,...

Specific features 4/5 Linear algebra –Greater dimensions –Kernel and rank functions –Eigenvectors and Eigenvalues

Specific features 5/5 Calculus –Advanced limits –Series convergence study –Power series expansions –Differential equations Finite fields
