Texas Instruments TI-83-Plus Silver Edition with Graph Link Cable Average Customer Review:  Electronics list price: $169.99 US | Canada | United Kingdom | Germany | France Editorial Review
Leery of "special edition" products, we regarded the TI-83 Plus Silver Edition with some healthy skepticism. It's silver--so what? As you may have noticed, in the post-iMac era, everything electronic seems to boast cool translucent or glittery casing. However, the features of the TI-83 Plus Silver Edition are substantial, offering useful, powerful extras at a remarkable value. While the mathematic and graphing tools are comparable to the TI-83 Plus, the Silver Edition boasts significantly improved speed and memory. Its processor is 2.5 times faster, and it has over 1.5 MB of memory--10 times that of the TI-83 Plus. These upgrades make the Silver Edition a significantly improved graphing tool, enabling you to work faster and save more of your equations and programs. Like the TI-83 Plus, the Silver Edition has a large, easy-to-read 64 x 96 pixel LCD that fits 16 characters and 8 lines. Altering the contrast of the screen is intuitively easy, as is the key layout and graphing interface. Mathematic tools are substantial, including viewing equations, graphs, and coordinates simultaneously; advanced statistics and regression analysis, graphical analysis, and data analysis; and tools for engineering, financial, logarithm, trigonometry, and hyperbolic functions. The calculator is ideal for students in algebra, calculus, and statistics, as well as those taking the PSAT/NMSQT, SAT I or II, and AP College Board Tests.
The calculator is also rich in tools for those studying biology, chemistry, or physics, including a pre-programmed periodic table. Other programs included with the calculator include a spreadsheet, organizer for phone numbers, puzzle pack, probability simulation, and CBL/CBR applications. The most exciting bonus of the Silver Edition is TI-Graph Link, which lets you connect the calculator to a computer and download programs from Texas Instruments' Web site (http://education.ti.com) and from enthusiast sites like www.ticalc.org. There you'll find thousands of programs and games for TI graphing calculators, as well as a TI-83 Plus tutorial, electronic guidebook, programming support, and discussion groups. The calculator uses four AAA batteries and one lithium battery for backup. All batteries are included, as well as a hard slide cover, the TI-Graph Link software and cable, and a remarkably readable 60-page instruction manual. Overall, the improved power, faster speed, and included TI-Graph Link for a remarkably low price make this a truly special "special edition," and we have to admit that the silver casing does look pretty cool. --Ariel Meadow Stallings ...

Texas Instruments TI-92 Plus Graphing Calculator Average Customer Review:  Electronics list price: $250.00 US | Canada | United Kingdom | Germany | France Editorial Review With more power than most of us had in our PCs less than 20 years ago, the TI-92 Plus graphing calculator is the machine of choice for students and engineers both at the desk and on the go. It comes with over 500 KB of memory and software for working through algebra and other mathematic problems quickly and easily. With the TI Graph Link accessory (not included), you can connect to computers and even download software upgrades. Solve linear and nonlinear equations, use the Pretty Print feature to see equations in textbook format, and work with 3-D surface graphs in real time. The QWERTY keyboard is rugged and easy to use, the 128 x 240 screen is easy on the eyes, and the calculator comes with a durable shell to protect its face when you're traveling or in the field. Additional accessories can turn the TI-92 into a mobile data-collection station, but it's just as useful at home.  Students beware: Some professors and teachers discourage, or even ban the use of calculators like the TI-92 in their classes, so make sure it's OK before you buy. Once you're set, the manual is clear and straightforward--you'll be programming in no time. Ultrageeks will love the assembly-language option, but the rest of us can get by just fine with the regular interface. The old timers might still cling to their slide rules, but anyone who needs a calculator for school or work can see why the Texas Instruments TI-92 is so popular: Its versatility, power, and portability give you the number-crunching power of a computer no matter where you are. --Rob Lightner Pros

Texas Instruments TI86 Graphing Calculator Average Customer Review: Electronics list price: $150.00 -- our price: $105.44 (price subject to change: see help) US | Canada | United Kingdom | Germany | France Editorial Review Designed with power users in mind, the TI-86 graphing calculator has all the power and functionality of the popular TI-85 but with significant enhancements aimed at students of college mathematics, engineering, and science. The TI-86 includes a function evaluation table, deep entry recall, seven different graph styles with multiple line and shading options, and slope and direction fields for differential equations. In addition, the TI-86 boasts 96 KB of user-available memory--three times more than the TI-85. There's also a new function evaluation table which shows numeric output for function, polar, parametric, and differential equation modes. The TI-86 runs with programs designed for the TI-85 and includes all the same matrix features, but with a new matrix editor that allows the user to view and edit matrices in two dimensions. You can also view multiple lists and attach formulas to those lists for automatic computations. A new aspect of the TI-86 is the ability to customize product functionality with machine language programs downloaded from TI's Web site.

I actually bought a TI-89 around soph year of college just to complement the TI-86. You see, the TI-86 is a SOLID engineering calculator. It's got fast units conversions, an intuitive and FAST menu system BUT it lacks "pretty print", handling of units for math (keeps the units throughout equations, calculators), and integration/differentiation with the variables in place (it doesn't just evaluate it). With the right software, the TI-89 is a very powerful math tool. I used the TI-89 primarily for theoretical math but came in handy for standardized tests as well. I would recommend getting both the TI-89 and TI-86 and start familiarizing yourself with both calculators before you start tackling tests. Check the rules and regs for calculators also - standardized tests should allow the use of the 86 and 89. Overall, the TI-86 is a solid math tool - notice I say TOOL because that's what it is. If you have no idea what you're doing in class, the TI-86 won't give you an A. My recommendation is to get both the TI-86 and TI-89. Also, slap in four 750mAH NiMH batteries. You will NOT regret this because these calculators drain alkaline batteries in half a semester of intensive use. We didn't have cheap NiMH batteries back in the day - TI actually pushed the use of Rayovac Renewals (remember those rechargeable alkalines that only lasted 5 charges?) and our other choice was NiCd. Forget all that. Slap in four Energizer 750mAh NiMH batteries and you'll save yourself a LOT of money in the long run. That means more money for video games and other forms of entertainment in college. ... Read more Asin: B00000JF53 |
