Using the TI-92Plus: Examples

We incorporated the use of the TI-92/92+/89 in order to help our engineering
students to use Computer Algebra in the classroom, not only in the labs.  We
will present live examples in order to make connections between subjects.  For
example :    we will solve equations using different methods and showing why
the Algebra menu of the TI-92 is a teaching tool ;  in multiple variable
calculus, we will look at Lagrange multipliers problems with the help of the
"zeros" function and 2D/3D graphics;  in ODE courses, we will focus on some
problems involving Laplace transforms/convolution, Fourier series,
slope/direction fields, numerical methods, chaos, ...
