Among all the Casio FX-991 models, FX-991EX is the best and most capable calculator for scientific calculations. FX-991 EX also gives tough competition to Texas Instruments’ finest calculator, the TI-36X Pro. The capabilities and features of FX-991EX are equal to TI-36X Pro and offer better response and intuitive performance than its TI counterpart. Expert Advice – Tips for Effectively Using the FE Exam Calculators This will display the Matrix Editor for input of the elements of the 2 × 2 matrix you specified for MatA.

Texas Instruments NCEES®-approved calculators, TI-30X and TI-36X, and all their respective models are readily available in the market. The 36X is a bit more expensive than its TI-30X counterpart but offers a much better display. If you want to copy MatA, for example, perform the following key operation: (MATRIX) (Data) (MatA). If you want to copy MatAns contents, perform the following to display the MatAns screen: (MATRIX) (MatAns) . Note, both of these calculators are defaulted to the RPN system (Reverse Polar Notation ... 5 enter, 5 +, equals 10). and it takes a bit to get used to. I like it better but it has a learning curve so if you're short of time, do not go this route. Remember that these NCEES®-approved calculators do not offer the RPN functionality (2 enter, 2 +, equals 4), and you need to train your mind and fingers to get used to this void. This will come as music to the ears of engineering students as they will likely be familiar with the TI user interface having used some version of their calculators throughout college.Press (MATRIX) (Data), and then, on the menu that appears,select the matrix variable you want to edit. Move the cursor to the cell that contains the element you want to change, input the new value, and then press . To prevent unauthorized transcription and distribution of the exam questions, calculators with communicating and text editing capabilities have been banned by the National Council of Examiners for Engineering and Surveying (aka NCEES). You may love the reverse Polish notation of your HP calculator; however, you’ll have to get used to one of the calculators NCEES has approved. The following operations are not supported by the Matrix Editor: , (M-), (STO). Pol, Rec, ÷R, and multi-statements also cannot be input with the Matrix Editor.

A range of potential aspects significantly impacts your FE exam performance and results. One vital factor is choosing the best approved calculator for the FE exam.

If you are using a new calculator, ensure that you go through all the important functions, understand its digital interface, learn how to access all the functions, and what are the default conversions methods. Some of the significant functions that you must explore for your FE exam include: In the Statistics Editor, move the cursor to the cell that contains the data you want to change, input the new data, and then press .

Replacements:

You can use either rectangular coordinates ( a+ b i) or polar coordinates ( r∠ θ) to input complex numbers. The first thing we want to mention about the differences between these similar calculators is their menu because if you are familiar with the 115ES Plus, pressing the menu will send you to a list of options while the 991EX has a set of icons to select. Selecting the option is also a bit different as you will need to press the corresponding number of each stated on the list but in the latter you will need to press the equal button. Press (STO), and then perform one of the following key operations to specify the copy destination: (MatA), (MatB), or (MatC). Computers and smartphones may be everything today but in some applications, you will not be allowed to use them, such as in a learning process. The one we can still utilize in such conditions and many other activities is calculator but not all calculators will be useful in your classes because different subjects and focus will need different tools as well to assist the lesson. In general there are basic calculators, business or finance calculators, and scientific calculators which are usually the most expensive and most complicated to use.

Both local and overseas companies have various leading models and the more people using the calculator, the easier to find a solution or learning materials. One of the best options when it comes to scientific calculators is the Japanese brand Casio because they are very good not only in quality but also the product reliability and performance. The price point itself is very much the same as similar models from other brands like TI or HP so students and parents don’t have to spend much to get the ideal calculator.

TI offers power-off memory preservation, unlike Casio. The most significant disadvantage of Casio is it erases the stored answer and calculation history if you accidentally power off the calculator or it turns off automatically after 7 minutes.

Use the Statistics Editor to input data. Perform the following key operation to display the Statistics Editor: (STAT/DIST) (Data).

Facts at a glance:

Use the same calculator during your FE exam preparation that you will use in the exam. It is crucial to get used to the calculator you will use in the exam. Most of us hardly skim the surface of what our devices are capable of, whether they are smartphones or calculators. Go to the depth of your calculator and explore all its features. Reviewing your user handbook and exploring the available functionalities will take a little time and effort.
