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

Originally bought a TI-89 Titanium and a TI-nspire CX 2 (Both with CAS) for school. Although it did everything and looked spiffy, 75%-90% of my classes didnt allow us to use it (apparently the CAS and other features do everything for you, who knew?). Once into my sophomore year (this year), something called COVID has placed most classes online making difficult to exclude those spiffy calculators. Any way we were told even though we may WANT to use the nspires and 89s, we need to get used to the calculators allowed on the FE exam. Enter the TI-36X Pro. This thing does just about every thing the spiffy ones can do, but still looks like those old solar powered ones you used to punch 58008 and tell someone to read upside down. Except this little bastard is powerful! Integrals, derivatives, vectors (dot and cross function in the vector menu, no need to write up a matrix and remember that ridiculous formula), solver, system solver for multi variables. This thing can do some serious damage even on a calc 3 exam, and its solar powered so you dont need to remember to charge it or bring spare batteries. Obviously the other beast calcs can graph and this cant. Other than that this thing is incredible for its price!!!! The only downside I would say is that it looks intimidating to use, and has a SLIGHT learning curve to it. BUT if you are going into a Science field and cant learn to use this, then you need to change your major ASAP!!! HIGHLY recommend getting this calculator for any college freshmen that will be majoring in Engineering, perfect for the student budget, and still can whoop some ass.

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.

This calculator calculates numbers correctly.

This calculator has complex number support (rectangular and polar form) and is usually sufficient for DC and AC circuit analysis. It has real matrix support but not complex matrix support so it can be used to solve systems of equations in mesh and nodal analysis in DC circuits but not AC circuits. In my experience most faculty dont require a calculator that can solve complex matrices in AC circuits.

Im a university junior computer science major. My workload is extremely math heavy. Almost four years ago when I started at community college, I knew nothing about advanced math, or calculators. I bought the cheapest calculator at Walmart which indicated that it was allowed for use on college tests, (SAT, ACT, etc.). I believe it was the Casio fx-115ES PLUS. Not a bad calculator, and comparable to this one, but it has many shortcomings IMO. A year or so later, by the time I started taking calculus classes I bought a graphing calculator, (ti-nSpire). I really enjoy that calculator too. I was turned onto the ti-36x pro by a professor I had a couple years ago. Since it basically fills the same niche has the Casio that I already have I never saw any reason to buy it. Besides, for the past few years Ive mostly relied on the nSpire. This Fall I began taking physics classes for some of my major requirements. The teacher doesnt allow the nSpire, or any CAS calculator on the tests. I like to use the same calculator in the coursework/homework that Ill be using on future tests, just to have that muscle memory when its showtime. I pulled out the old Casio and dusted it off, and after the past few years with the ti-nSpire, lets just say I was less than inspired by using the Casio. The biggest thing that I dislike about the Casio is that you can only see the present problem that youre working on at any given time. I got used to being able to scroll up and see previous problems/solutions, and being able to navigate the cursor up to a previous solution, press enter, and have it inserted into another equation, or whatever that Im currently working on. Hopefully that makes sense. In any event, the ti-36x pro does this too! You can see the three most recent problems that you last worked on, in addition to the one youre currently working on. And you can scroll back to any spot in the history, up until the point where you last cleared it. You can also easily insert solutions, or portions of previous problems into the current. For me this is crucial during test taking. It is the best type of calculator work flow for myself, and although something similar to this can be achieved with the Casio, I was never able to get it to work with out feeling cumbersome. There are several other things that I like about this calculator over the Casio as well. In some aspects I like it even more than the ti-nSpire. Mostly just because using this calculator is so smooth and simple. If I dont need to take limits, anti-derivatives, or indefinite integrals, or plot actual graphs, I would choose the ti 36x pro over the nSpire, just because it is so simple and elegant to use. Ive not used a ti-84 much. Never owned one, but have played with them a few times. As far as I can tell, this thing is basically a ti-84, without graphing capabilities. In short, if you need a calculator for algebra, engineering, physics, trig, some calculus, etc., but you cant use a full fledged CAS, or even a regular graphing calculator, this is the best option.

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.

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.

College-age daughter told me the TI-83+ I bought in the 1990s finally failed, Sunday night before a Calculus test. We werent sure about borrowing one from the testing center, so ordered this for overnight delivery hoping it would show up before the test at 10 AM. It did! She says it does everything she needed the 83+ for, and its even solar powered so not a battery hog (it does have batteries as well).

I had used a TI-83+ for about 8 years. When I signed up to take my Fundamentals of Engineering review, they limit which calculators can be used and the one I was used to wasnt allowed. However, this one was. I had such an easy transition to using this one and it saved me on multiple occasions during the exam (especially the definite integral and matrices features).

Classic TI calculator. Does the job.
