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

I needed to take a math class called Elements of Calculus. It covers Elementary Functions, Finite Mathematics and single variable Calculus. This is the book

Great for what you need it for.. it’s barebones but works for 99% of standardized testing and college math/chemistry classes.

Muy funcional

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

I’m in pre cal and my professor won’t allow us to use graphing calculators, so I’ve looked around at several different scientific calculators and While there are a ton of features the pro should have, overall it does include everything you need plus a few enhancement tools, like the solver, and it’s ability to provide exact and irrational answers. Although the pro is hands down the best scientific calculator on the market, it could definitely use some upgrades to make life easier. 1. I wish it allowed you to create a table for more than one function at a time for comparison purposes. 2. Formula memory!! Why does this only have one formula memory slot? (FYI there is a scientific calculator from Sharp that allows you to store up to 4 formulas but it doesn’t have a table mode.) 3. QR codes. I came across the Casio class wiz scientific calculator and it lets you generate a qr code from a table you created and view its graph from your phone. It also has a spreadsheet function. Only didn’t buy because it erases your work once it turns off. I love that you can turn off the TI 36xpro and when you turn it back on again, all your calculations are still there. 4) >,=, and < signs. When I’m making tables, sometimes I only want to see results within a specific range so being able to tell the calculator you’re only looking for values within a desired range would be significantly helpful!

The reason I purchased this calculator is because I needed one for the FE exam. I was contemplating buying this calculator or the casio fx-115 (or whatever its called). I decided to buy this one because Ive been using TIs for a long time and figured the learning curve wouldnt be as bad. I dont know how it stacks up to the casio - I probably would have been satisfied with either calculator and when choosing calculators its probably more of a matter of picking a preference than picking a calculator thats better than the competitors. In any case Im quite satisfied with this purchase. As I expected, because Ive used TIs as long as I have it was quite easy to pick up on where all the keys were and how to operate the calculator - its very intuitive to operate. The calculator also provides some nice programs. For example Im able to put in a list of numbers and have the calculator automatically calculate all sorts of statistics pertaining to that list (i.e. standard deviation, sample standard deviation, average, etc.). None of those are hard to manually calculate but it can be quite tedious to calculate the standard deviation manually with a long list so its nice that the calculator does it for you. I almost felt like I was cheating on the FE exam when I was using this feature. some other calculations this calculator can perform are integrals/derivatives (I dont think it allows indefinite forms of integrals/derivatives but maybe I just dont know how yet), nCr, nPr, rectangular to polar conversion and vice versa, vector cross/dot products, calculations involving matrices with dimensions up to 3x3, 2nd/3rd order polynomial equation solver. Theres a fairly useful list of constants as well. One thing that bugs me about the constants is that theyre all listed as one long list and the units corresponding to that list of constants are listed in another list. For example if I want to use the constant of gravitational acceleration then I find it in the list of constants. I press enter and obtain 9.80665. If I were to want to know what units its in then I have to go the the list of constants, hit right on the directional pad, and find that constant again to find out that the units are m/s^2. This can get pretty annoying. The conversion program is quite useful and has an abundant number of choices to choose from (English to SI, temperature, velocity, etc.). A minor but very useful feature of this calculator is the ability to scroll through previously entered inputs and previously obtained answers and selecting them so that they appear on the input line (think of the TI89, unlike the TI83). The answers appear as fractions by default, like in the TI89. Hitting the conversion fraction/decimal key once allows you to toggle between whether the answer is displayed as a fraction or decimal. I didnt really find the 1 and 2 star reviews to have any merit (I didnt read the 3 star reviews). I didnt find the metallic keys giving me any hassle. Overall this calculator was a great purchase and Im going to continue using it even after having passed (hopefully - still awaiting my results) my FE exam. Edit 10/19/2012: I Passed my FE exam (first try despite the delay between my first post and subsequent editing). One other nuisance I found with the calculator is that it doesnt show commas for long numbers and it cuts off many significant figures for small numbers (for e.g. 2.1e-9 gets displayed as .000000002). Im still using my ti-36 pro and am happy with my purchase despite this nuisance.

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.

For taking NCEES licensing exams, such as the FE and PE, this TI-36X Pro is one of the better calculator options. There are a couple caveats that make this a 3/5 at most though. First, the screen. It has nowhere near the contrast shown in the photos. Mine is sorta blueish and hard to read unless there is light right behind you. Its also very blocky and pixelated looking. Second, the right column of metalic buttons are just awful. Hard to read unless there is just the right lighting. It seems there is a much better TI calculator option, the TI-30X Pro Mathprint. However wasnt positive if that is allowed on the licensing exams (although it should be, they do say All TI-30X and TI-36X models)... so I bought this.

The picture shows silver flat keys with blackened math functioned symbols, but the one I got has total chrome keys and the symbols are not blackened out. The math function keys are difficult to see unless the light hits them just right,. I bought this calculator because it is approved for taking to my Ham Radio license test. I tested the calculators functionality against my 20 year old HP graphing calculator and a the math seems accurate .. at least for engineering. I like the rest of the calculator; fits good in the hands and the display is easy to read, but why the engineers would have ever gone with chrome math function keys is beyond me. They must have wanted to make it look cool, but cool it is not. Im going to keep it as it does what I need it to do, but I will be filling in the symbols with flat black so I can see them. if you find this calculator with different color keys, get it, or maybe find an older model. If you expect perfection, then pass on the calculator. Shame on the Engineers.. and to TI for allowing it to go out like this. They should try using it before putting it out on the production line.

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).
