TI-84 Plus Graphing Calculator for Dummies

If you have a T1-84 Plus Graphing Calculator, you have a powerful, sophisticated tool for advanced math. In fact, it’s so sophisticated that you may not know how to take advantage of many of its features and functions. That’s a good problem to have, and TI-84 Plus Graphing Calculator For Dummies is the right solution! It takes the TI-84 Plus to the next power, showing you how to:
Display numbers in normal, scientific, or engineering notations
Perform basic calculations, deal with angles, and solve equations
Create and investigate geometric figures
Graph functions, inequalities, or transformations of functions
Create stat plots and analyze statistical data
Create probability experiments like tossing coins, rolling dice, and so on
Save calculator files on your computer
Add applications to your calculator so that it can do even more
TI-84 Plus Graphing Calculator For Dummies was written by C.C. Edwards, author of TI-83 Plus Graphing Calculator For Dummies, who has a Ph.D. in mathematics and teaches on the undergraduate and graduate levels. The book doesn’t delve into high math, but it does use appropriate math examples to help you delve into:
Using the Equation Solver
Using GeoMaster and its menu bar to construct lines, segments, rays, vectors, circles, polygons, perpendicular and parallel lines, and more
Creating a slide show of transformations of a graph
Using the Inequality Graphing application to enter and graph inequalities and solve linear programming problems
There’s even a handy tear-out cheat sheet to remind you of important keystrokes and special menus, And since you’ll quickly get comfortable with the built-in applications, there’s a list of ten more you can download and install on your calculator so it can do even more! TI-84 Plus Graphing Calculator For Dummies is full of ways to increase the value of your TI–84 Plus exponentially.

This was described as portable by my maths course (OU MU120). Personally I think it's about as portable as a brick but there are loads of cool features so they're forgiven! My only problem now is I keep getting it mixed up with the sky button box.

Algebra is much easier to teach when your students can work through the self-directed lessons in this book. Students can explore mathematical concepts on the TI-84 Plus while you walk around the room and facilitate their learning. Keying sequences guide them through the labyrinth of menus on the TI-84 Plus without the need to page through the calculator manual. Detailed solutions at the back of the book help students over obstacles to their learning and the calculator functions are absorbed with minimal effort as the mathematics is learned. Some programs are included to showcase the power of iteration in solving some otherwise intractable problems. Historical vignettes are included to add a human dimension to the mathematical excursions. The topics include sequences & series, finding roots of polynomial equations, the fundamental theorem of algebra, complex numbers, fractals and mathematics of chaos, combinatorics, probability, linear systems, matrices, linear programming and various applications such as the mathematics of investment. A new section on Phi and the Golden Ratio has been added for current interest stimulated by The DaVinci Code. For those with the TI-84 Plus Silver Edition, this book includes references to the probability simulations involving coin and dice tossing experiments found on the Applications menu.
