Texas Instruments TI-36X Pro Engineering/Scientific Calculator | 9.7 Inch | Black.

As a current highschooler I needed a calculator. Of course this is possibly the most common one around and for good reason. It’s very easy to use and I haven’t had any problems with using one. Very worth it

Its a great calculator, here is what i can and cant do as an tech student. Cheap, just 20 bucks. And if id had it before, life wouldve been way much easier, soon i wont need it anyway, since ill be doing signal processing. CAN DO: -Operate determinant, inverse , transpose, Identity matrix., operate in a straight line all your matrices. -Circuit Solve of three variables, you can simplify the circuit and solve the corresponding equations faster than a setup in matlab. -Vector operations, Constants! a ton of constants that you will need... Ke for example for electrical fields. -Not a cheat calculator but you can store results AND operations in the many variables it has (x,y,z,a,b,c and i think it has d too) -Statistical regression and stuff i didnt bother to read since i wont use. - Operate definite integrals with base x, just change whatever variable you have in terms of X. -It has all the inverse and hyperbolic trigonometrics functions which is just wonderful... CANT DO - Operate indefinite integrals, this is super important since many times youll be solving triple or double integrals and find yourself in a messy chore solving the indefinite and then the definite. - Cant operate variables in matrices, extremely tricky matrices may include variables, so you might want to input them just to know they cant be operated. - Cant operate transforms. This one ... i think they chose it to be this way because this calculator feels more than capable of doing this, just as the definite integral yet still its impossible, it doesnt even have a menu for that. THIS CALCULATOR WILL BE USEFUL FOR: BASIC CIRCUITRY INCLUDING AC, since it can change to polar and fasor. Linear Algebra Vector Mathematiccs Definite integral calculus Definite Differential Calculus Normal Algebra , just normal stuff... WONT BE USEFUL FOR: Indefinite integral and differential calculus. Multivariable Calculus Anything related to transforms , anything at all.

This calculator was worth it! It was easy to use and due to its popularity you can find a YouTube video detailing just about any operation you want. I recommend it for statistics. I tried using a BA II+ financial calculator, but it did not have the decimal places needed for statistics nor did it have the ability to show multi-line. The TI36X-Pro cut my homework time down by hours per week. Working a problem on my calculator, I found the TI36x to be 5 to 10x faster than my BAII or the default windows calculator I was trying to use before. I am working through an MBA program and have been out of school for 15 years, so I currently consider myself a novice user. I received this calculator 3 days before my midterm, and it was easy to relearn within that time. I cant stress enough just how much easier this calculator is to use for statistics. It automatically calculates Standard Deviation, Median, Mean, quartiles, etc from a single variable set. It does MUCH more, but that is all I have studied so far. It also allows you to recall a formula you entered previously and change it... great for figuring +/- confidence intervals.

So, I needed this 36X for a Calculus based Physics-2 class. Who knows why this teacher allows this, but not the graphing type calculators. This does so much of what my N-Spire does. Sure, the N-Spire CASdoes more, but really, I just dont think it does much more that gets used on a daily basis. In fact, Ive been using my TI-36X now more and more as a daily driver. When I want to plug and chug numbers, the TI-36X is now my go to calculator. Most of the time, the TI N-Spire just made things take longer to do. Even turning the thing on takes longer. It was like the N-Spire CAS did so much, that it was just in its own way. At that point its in my way. I need to take a class on how to use it. I bought an instructional book and its like 500 pages thick. Matrices; I gave up and grabbed my TI-84. The TI 36X to me is just a higher end, plain old scientific calculator. It doesnt graph, which is kind of its thing because it does just about everything else. Diff Eq., Systems of Eq., vectors (dot and cross products), Integrals, derivatives, blah, blah, blah. It just doesnt have a graphing function. If youre kind of past that, then this will do you just fine. If you dont need it, but need something with more higher end functions, then this is good. I came from a TI-84 and used it for everything for years. It was fine. I thought the N-spire was a step up, but I personally have found that I just need a solid, predictable, easy calculator, and this 36X seems to fit the bill. I motor through Thermodynamics, Physics-2 and Differential equations now no problem. That makes me happy. Its light, its solar, its got a little bigger screen than most, and its easy. Oh, and really cheap at $20! Thats 15% of what I paid for my TI N-Spire CAS. Unless we can work out our differences through better communication and counseling, I have a feeling there is going to be a N-Spire CAS divorce here soon...

I had these for my years in highschool and now in college. it is the most reliable calculator out there with many of the basic functions. I believe everyone should use these on SATs because of their practicality.

Im not sure if they allow this type of calculator for the ACT. But it works well altough there are a few things I cant figure out. It helps a lot and its simple to use once you figure out where everything is but for right now Ill keep struggling.

The calculator is very good overall. My only complaints are with things such as decimal to degrees/mins/seconds and vica versa. You have to navigate a bunch of menus to this basic conversion. It is actually faster to simple divide by 60 then 3600 to find the mins and seconds then to navigate the menus. The calculator suffers from not having a simply button to convert back and forth. Like a dec -> DMS button would be a huge welcome. Especially since this calculator is primarily used on the EIT/PE and LSIT/PLS exams.

This calculator was an upgrade from my son’s middle school one (TI-30xiis). I was looking for something that would carry him into advanced math and even college maths, without being a full-functioning expensive graphing calculator. So far, straight out of the package, I can already see that it was a good choice to upgrade. It has more functions, a user guide cheat sheet in the lid, rubberized grips both on the calculator and lid, a larger display screen, and more. The function buttons are NOT metallic as shown and mentioned in older reviews. See pics.

I had an old TI-30X that I was using for a while. I recently picked up the TI-36x and its functions have been a gamechanger for my engineering classes.

For this review, Im going to be comparing the TI-36X Pro (from here on shortened to TI for the sake of brevity) and the Casio fx-115 ES (shorted to Casio). Both calculators are excellent, but whether or not the TIs shortcomings make up for the Casios features is up for debate. ------------------------------ What I like about the TI The buttons. Theyre far more clicky on the TI then on the Casio. Dont get me wrong, the Casios button are still pretty good, but theyre inferior to the TIs buttons. Calculation history. When you turn off the TI, all of the calculations youve done are saved inside the calculators memory. For example, you enter 2+2 and press enter. You then turn off the calculator. When you turn the calculator back on, you can scroll up and find that calculation saved, results and all. Add in the fact that this calculator even saves calculations that results in errors, and this calculator could be a potentially useful way to cheat on tests. Take the quadratic formula as a example, you can type it into the calculator a couple minutes before you take a test over it and pull it up right when your proctor walks away. Once you have it written down on your test, you can just clear the TIs memory and itll then be impossible to prove youre cheating. Im not saying you should do this, Im just saying you could do this. The Casio instantly erases your history the second you turn it off. It also does not save any calculations that results in a error. The anti-slip pads on the back. I have no idea what those little pads are called, but thats what Ill call them. Basically, there are four little pads on the back of the TI which creates friction and makes it almost impossible for the TI to slide on slick surfaces. The Casios plastic casing wouldve instantly slipped from the surface of a slick, angled surface. (It doesnt necessarily have to be a slick surface, just any surface that doesnt create friction, such as a wooden surface thats been waxed) ------------------------------- What I dont like about the TI The third button. On this calculator, Texas Instruments (the manufacturer of the TI) decided to put in a peculiar take on multi-purpose buttons. For example, there is one key on this calculator that, with one tap, inserts x, two taps inserts y, and so on. (x, y, z, t, a, b, c, d) There is also a 2nd button that, if clicked in conjunction with the previously mentioned button, brings up the clear var dialog. Because of that, a single button on this calculator could potentially do eight different functions. The Casio only has 1st, 2nd, and 3rd buttons. The maximum number of functions a button on the Casio could do is three. The way Texas Instruments decided to implement mixed fractions. I dont really want to get all technical, and someone else can probably explain the problem far better then I could. Just do a Google search for Supposed TI-36X Pro Error. (Include the parenthesis. Yes, you heard that right, include the parenthesis.) In practice, I dont find that bug to be very bothersome. I rarely use mixed fractions. The Casio doesnt exhibit this problem. ------------------------------ Overall, you cant go wrong with either calculators. Its just a matter of whether or not youre willing to accept the TIs faults in exchange for its features. The price difference is negligible, at least at the time of writing. The TI was more expensive by about $5.
