TI-Nspire­ CAS in Engineering Mathematics: Systems of Three Linear Equation in Three Unknowns

Addressing the (simple) case of a unique solution and both explicit plotting and parametric 3D plotting

Publisher: T³ Europe

Author: T³ Europe, Michel Beaudin

Topic:  STEM

Tags  Linear regression ,  Modelling ,  System of linear equations

Some TI-Nspire CAS commands, such as solve, linsolve and rref are used to find the intersection point of 3 planes. This tns file deals with the (simple) case of a unique solution and both explicit plotting and parametric 3D plotting are used. This file can be used in a linear algebra course where students have been introduced to 3D plotting.
