I personally own a copy of this book. It's great and gives step by step clear directions for how to use any feature of
the TI-83 Plus. Almost every example has multple screen shots from the TI-83 Plus.
- For many people the advanced statistics capability of the Ti-83 Plus will be the strongest reason to buy it.
If you plan to take a statistics class, you will probably find that this the TI-83 plus is worth the slightly higher price than it would cost to buy a TI-83(regular not plus!). The statistics features of this calculator set it apart from earlier models and, surprisingly enough, later TI's including the TI-86, 89, and 92 ! This model can do a Chi-Square and various descriptive stats, confidence levels, hypothesis testing and probability distributions. You might find yourself wondering when the heck you'd have to do a Chi-Square and the answer is in a "Stats class."
-Like majority of the Texas Instruments Calcuators, the TI 83 plus graphs functions allows for polor or regular coordinate graphs,allows you to change the window, the scale of the graph, gives you zoom in and out as well as 'trace' the graph feature and the 83 plus can produce stat graphs like the box and whiskers, histograms, scatter plots as well as regressions.
Additionally, it is possible to save and recall graphs at a later time. A really cool feature that this calculator can do is: given a function like y =2x, you can have the TI-83 plus produce the graph of its inverse function!
Calculus - Unlike the later editions the 89 or 92, this calculator does not do all of the symbolic integration and differentation. The 83 plus can compute derivatives and do integration for
Complex Numbers- you can do all the operations with complex numbers :addition, subtraction, multiplication, exponents etc. The calculator for instance can simplify powers of i . Other features of the TI-83 Plusinclude: finding the conjugate of a complex number, finding the polar angle and modulus of a complex number, convert
Economics & Finance -The TI-83 plus can calculate effective rate, nominal rate, and has a neat feature called the TVM solver which can be used to calcualte total number of payments, the annual interest rate, principal, etc...
Linear Algebra - Personally, when I took linear algebra in grad school last year, the linear algebra capabailties were a great reason to buy a TI-83 plus calculator. This calc can multiply matrices as well as add and subtract them. Also, it can produce the inverse of a matrix, produce reduced row echelon form for a matrix and calculate the determinant.(It should be noted that the regular TI-83 has these features--you just press a few different buttons)
Probability - Permutations, combinations, generating random numbers, probability distributions including binomial
, poisson, normal, chi-square, F.
Sequences - The 83-plus has many features that support sequences. However, you should know that the the TI-83 plus can work withy only three sequence functions, each function can only work with the prior two terms of that (or another) function. Therefore, the calc can do a Fibonacci sequence of x(n) = x(n-1)+ x(n-2) but that is it. However, the 83 plus lets you graph sequences or multiple sequences, store sequences for later use, and show the values of a sequence in a table
Applications - The following applications are available for download at the TI site
Advanced Finance: high power financial calculations
Cabri Jr. - Interactive geometry software
Catalog Help - provides syntax you need to be able to enter the argument for different calculator functions
CellSheet - Spread sheet program for your calculator. You can also download the freely avaible TI CellSheet Converter software to transfer your spreadsheets from your calculator and Microsoft Excel or AppleWorks. CellSheet also converts in the other direction : from your computer to your calculator.
GeoMasater - Geometry program that draws circles and polygons and can perform transformations
