First off I would highly recommend purchasing the Guerrilla Screen Protector . Many other reviewers mention their screen getting scratches or smudges -- the screen protector will make that a non-issue for you. Another thing, the slide cover that comes with the calculator should be sufficient to keep it from being damaged.
Regarding the functionality and capabilities of this calculator...wow was my first response. This calculator is well suited for high school as well as university students. Even instructors could use some of its features to demonstrate certain mathematics to the students as the calculator can be connected to a computer and from there a projector may be used.
The rechargeable battery is really very awesome imo. You will get many hours of use before you have to re-charge the battery and even when you do it is quick -- the calculator is also smart about conserving energy and it will dim the screen and then turn off if left to idle for a while.
Resolution of the screen is such that if you look closely you will be able to see the individual pixels, however the colors are vibrant and add a whole another dimension to a calculator. It is difficult to explain but if you've been using a regular graphing calculator for years and years once you start working with this one you will be amazed.
Some of the functions available under each subject section;
- Calculus: Derivatives & Integrals (definite and indefinite), Limits, Sums, Function min. and max, normal and tangent lines, arc length, series, Differential Equation Solver, implicit differentiation...and more
- Algebra: completing the square, expansion, solve system of equations, polynomial tools, trig, complex...
- Probability: permutations, factorial, distributions...
- Statistics: stat calculations (just a ton of them), List math & operations, distributions, confidence intervals, stat tests...
- Matrix & Vector: determinant, row-echelon form (and reduced), row & element operations, cross and dot product for vectors, conversion a vector to polar, rect.,cylindrical, spherical...
- Finance: TVM, amortization, cash flow, interest conversion...
That's only a small fraction of what it can do, and it doesn't even include the ridiculous number of graphing features and tweaks. I could praise this calculator and nerd out about it all day.
However there are certain things I do not like or find bothersome. Right off the bat, please Texas Instruments include a full and detailed manual along this calculator. I know there are is a pdf online but it would be so much nicer and imo professional to have an actual physical copy I can refer to when needed. The other thing is the touch-sensitive pad in the middle of the directional button; I find it sometimes to be too sensitive and it can make navigation more difficult when I am trying to use only the arrows and keep accidentally swiping over the touch-sensitive pad. In fairness I should also mention that the touch-sensitive pad is really great when you actually DO want to use it. One more thing, pretty dumb and very unlikely a sentiment shared by many others, I do not like the fact that the buttons for the letters are arranged in an alphabetical order. Yes it makes sense; however many people, myself included, are entirely accustomed to the QWERTY layout and it can be difficult to type with the same proficiency when using this calculator to take notes or something like that.
As a final note I just want to say that this is a very feature-rich and complex calculator. You will HAVE TO at least skim through their online manual to figure out how to perform certain tasks, but I guarantee you that when you get proficient at using this calculator you will be able to deal with quite complex problems easily. Not only deal with them but also graph and display the results in a manner that can show exactly how your data/numbers are behaving.
Do not make the mistake of assuming this is for high-school kids or college sophomores only.
Pros:
Insanely advanced functionality, with the ability to simplify, factor, find GCF, LCM, and remainder, distribute (called expand on the calc), find zero's, simplify fractions, solve for X, find derivatives, derivative at a point, definite integrals, and probably so much more that I have not explored yet! Much of this is thanks to the CAS built in.
Maybe one of the coolest features is the ability to have spreadsheets and documents on it, allowing one to store important formulas and equations.
It also graphed functions relatively quickly, although the 'drag' with touchpad is painfully slow for more complicated functions and the processor struggles to keep up. 3D graphs work although it is a bit sluggish and low resolution.
Cons:
Although it is a color screen, I wish for $140 they could use a VGA (640*480) resolution and an more powerful microprocessor/GPU. This will eliminate much of the lag when dragging graphs. They should have also added a speaker since one of the neat things this can do is games like snake or pacman! I can't imagine a better chipset costing more, they could have gone for a outdated smartphone 800MHz single core ARMv6 processor and 512mb RAM. After all, the raspberry pie is only $30 and that has similar hardware!
Overall I see this as a great value, one of the best calculators on the market, and a good tool to have for any advanced level of math! (this will not be suitable for those who have not passed algebra 2 since this it would defeat the purpose of learning how to do stuff on-paper. So it is a good idea to check with professors and testing centers if this is allowed.)
