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

- Logs - change
of base
- Analyzing the asymptotic
behavior of a function (example 2)
- Finding a zero
(root of a function)
- Finding a minimum
or maximum
value of a function
- Finding where two graphs of functions intersect
- Graphing a piecewise
graph, and the greatest
integer function
- Graphing a circle
- Graphing an inverse
- Graphing a tangent
line to a curve
- Regression
