Need a graphing calculator? I recommend one of these:
The Praxis II 0061 and 0069 exams specifically permit you to bring and use
a graphing calculator. 0061 REQUIRES a graphing calculator, and 0069 PERMITS a graphing calculator. Consult your individual exam instructions for the
details. Some general info is found here:
For the Praxis II Math exams, the student is expected to use technology (namely, a graphing calculator) appropriately as a tool for problem solving.
If you have never used one before, you will be amazed at how powerful a tool
these calculators are. For example, they will plot curves, find zeroes, and
invert matrices, so you do not need to do these things manually.
Consult your individual exam instructions for specific graphing calculators
that are permitted. I like the Texas Instrument series (I use the 84 Plus); sometimes they even can be found used. You can get one here:
Some of the links above are to the TI Graphing Calculator for Dummies
book series. You can download the official TI manual from their website,
but it is absolutely massive. You can more quickly find what you need from
the Dummies book, which I have used and is very well written.
I understand that the TI N-Spire and the N-Spire CAS (computer algebra system) are
not permissible calculators.
