There are many ways to use the TI-86 in algebra, trigonometry, and calculus. A number of these are covered in this tutorial. Many of the topics are applicable to more than one of the courses. Many of these examples depend on your being able to properly enter a function.

Algebra

  1. Logs - change of base
  2. Analyzing the asymptotic behavior of a function (example 2)
  3. Finding a zero (root of a function)
  4. Finding a minimum or maximum value of a function
  5. Finding where two graphs of functions intersect
  6. Graphing a piecewise graph, and the greatest integer function
  7. Graphing a circle
  8. Graphing an inverse
  9. Graphing a tangent line to a curve
  10. Regression
  11. Solving a system of equations with a matrix
  12. Solving a system of equations with SIMULT
