Texas Instruments TI-36 X Pro Scientific Calculator

Been using it for around a year. The product feels uncomfortable if you are a casio buff. But, the product is excellent, its just a matter of getting used to the keys and position of the various buttons. It does take some time getting used to but totally worth it. I have a two casios 991ms and fx72, but this is the best that I could get for the same price. Remember the function keys are silver and not easily discern able, so, you can use a nail polish or some kind of paint which goes into the grooves and the keys are highlighted. The cover is a little cumbersome to operate. But, it fits the bill for me an excellent product from TI and my first calculator was also a TI in the late 80s.

A beautiful calculator, smoothest experience compared to the ones I have used.(casio 991ES and the Fx 82ms)>>>The +plus es:It’s mainly targeted toward algebraic calculations. Calculations involving lots of 10powers(like eltronic charges) are easy with EE button. Log,ln, and custom multi tap one button and more importantly you can go to your operations history and find the value of any line at any moment, which is not possible with the casio. Greatly useful when you get an error, or you want to calculate with a new set of values.There’s also a ‘setop’ function that helps to do common operational patterns with the press of a button. For example if you’re working with problems that involve numerous area of circle calculations, you can simply save an operator as pi*r^2 into that button. It’ll operate on any value and give a result without having to type the whole line every time.Storing temp values to variables and using them are much easier with this.Built in convert to different measurement units sometimes come in real handy(it also has some built in popular universal constants too, like value of k etc. just in case)Most importantly display has more size and it becomes real easy when you’re doing lengthier step calculations.And yes turning off the calc doesn’t erase your history, that’s good if you take a break in between.>>>The -minus es:So far so good, but this has some limitations. Once you move out of the typicsl algebraic field things get a bit lengthier with this. For example general arithmetic problems could get more time consuming since the square and under-root are now clubbed into one button. You need to first place ‘2nd’ then the square root to do that operation.Matrix size is limited to 3X3 instead of Casio's 4X4.I shall update if I encounter furtherConclusion:Overall I’m satisfied with the product. I’m a BTech graduate so a good calc was needed. i would pick this over 991EX or ES. My calculations time has greatly saved. The price could be a bit lowered I guess, but texas is a marked brand in this field so I’m not surprised to see what they’re asking for this product. Overall definitely recommended.

it is equivalent to casio 991 ES and 991 EX except a few feature. both - and (-) minus sign may confuse you. first sign is used in term sepatation but can not be put before first term and can be used to minus something from answer or last entry and on the other hand second sign is used for sin of negative angle, for negative element of matrix, negative exponent and so on.A single key but can handle many function by multiple pressing for examle sin, sin-1, sinh, sinh-1. It is only oprated by battery (with life about one year) not solar. it can work as exel of 3 coulumn upto 48 row to make table and very fast to calculate all statistical variable at one time. It is not easy to operate first time. Watch some vedio on you tube to operate it. If you find any difficulty in any operation or funtion see manual also.

The product is working fine. However, after using this product, migrating to other calculators becomes little difficult.I used Casio fx991es plus, I lost it, hence bought this one for change. It never disappointed me unless for minor glitches.PROS:Conversion from complex to polar, and the other way round is easier compared to Casio FX991.Working with matrices is very easy and you will find it better to use this over CasioThe calculator stores the last calculations more than 20, so you can can access them very easily.You can solve equations with ease, store values of variables and evaluate polynomials.(upto 3rd degree)Conversion from HEX to Binary, that is changing number bases is so simple.It makes it easier to access hyperbolic functions, believe me I was 5 times faster than my friends, who used Casios, in my class.Cons:You need to hold 2nd button(like shift in Casio) for some simple square root calculations, exponent functions and for using the answer.There are two buttons CLEAR and DELETE it is often confusing to use them, clear is more intensive, it wipes out entire equation which you are typing and delete is little intensive it will remove only one character. Beginners may take time to adjust.There are two minus signs, one is to be used to start a equation or number with "-" and other to use in remaining calculations.The first minus key is also assigned with the answer key , hence you need to use 2nd button for accessing answer every-time.AND Editing the equations is very hard, here Casio wins. Once you type the equation editing is not easy unless the character has same no.of spaces to fill, adding brackets while editing the previous equation will slow you down.

It's really good

I have used 3-4 Casio calculators in past, this one is better than them in some aspect. it's light weight, has wide screen, three years warranty, more functions, better solar cell(at least that's how it appear), etc.the only issue is it's MRP is 1130 and 100rs is for delivery, in market you generally get 10-15%discount on such electronic products, so u will probably get it in 900-1000. but still a good buy from here.
