About this deal

With a lot of brain work already involved in the FE exam, you can only afford to do simple calculations manually. It will weaken your focus on the core exam areas and drain your limited time to complete your FE exam. Pressing any one of the following keys while the MatAns screen is displayed will switch automatically to the calculation screen: , , , , , , ( x 3). The calculation screen will show the MatAns variable followed by the operator or function for the key you pressed. t: This function is preceded by the argument X, and determines the normalized variate X t = X- x σ x. 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.

Many people choose this option when they have prepared extensively in advance. Others need less time to review (e.g. college seniors), so they have time to learn how to utilize the equations and the HP. The Casio fx-115 ES Plus is the most advanced solar-plus-battery scientific calculator that provides long life and dependability. This also means that you don’t have to live with the fear of your calculator dying midway through your exam.

Replacements:

It won’t take you very long to skim through the topics to find functions and commands that will help speed up your problem solving. Remember: the goal is to figure out how to get the most out of it for the FE exam. While the Statistics Calculation Screen is on the display, press (STAT/DIST) to display the Statistics Menu. The corresponding x-value (two values, x 1 and x 2, in the case of quadratic regression) also can be calculated for a value of y in the regression formula. To insert the MatAns variable into a calculation, perform the following key operation: (MATRIX) (MatAns). Move the cursor to the cell that contains the element you want to change, input the new value, and then press .

Press (MATRIX) (Data), and then, on the menu that appears,select the matrix variable you want to edit. 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. 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) . 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.As the same type, these calculators will also work in the same manner and there are tons of functions here to try and use. For example let’s use the fraction function to solve a problem which is also going to use parenthesis. They are easy to use combined with the Math view making the problems appear the same to those we see in the book. Type a quadratic formula like 4+42-4(1)(2)2(1) use the arrow to navigate the box and when done, just press equal button then you will be shown the result which is 2+√2 . Example 4: To determine the estimate value for x when y = -130 in the regression formula produced by logarithmic regression of the data in Example 3. Specify Fix 3 for the result. (Perform the following operation after completing the operations in Example 3.) Press (STO), and then perform one of the following key operations to specify the copy destination: (MatA), (MatB), or (MatC). This will display the Matrix Editor for input of the elements of the 2 × 2 matrix you specified for MatA. You should start using one of these approved calculators at the beginning of your study preparation, so that you are familiar enough with it by the time of the exam. Please note that the list of approved calculators is reviewed annually. All of the articles we pulled information from for this post are listed at the bottom of this article. The following calculator models are the only ones acceptable for use during the 2021 exams, as of the publication of this video:

If you are here then it means you will need a scientific calculator and with almost endless options out there, the shopping may not be going to be a short trip especially for those who want to get the best option out of their budget. Any scientific calculator will be able to work with scientific problems but we prefer those from well-known manufacturers just because they have better build quality and it is easier to find a solution in case we will be facing certain issues with the product later. Below are some vital tips that will help you further handle your calculator with limited chances of mistakes during your FE exam. Example 3: To calculate the linear regression and logarithmic regression correlation coefficients for the following paired-variable data and determine the regression formula for the strongest correlation: ( x, y) = (20, 3150), (110, 7310), (200, 8800), (290, 9310). Specify Fix 3 (three decimal places) for results.While single-variable statistical calculation is selected, you can perform normal distribution calculation using the functions shown below from the menu that appears when you perform the following key operation: (STAT/DIST) (Distr). Understand and practice the layout of the buttons to help save time and avoid errors during the subconscious use of the calculator in the exam. While some problems are “plug and chug,” you must still plug in all those numbers. Even the most minor error can cost you valuable time. Whenever the result of a calculation executed in the MATRIX Mode is a matrix, the MatAns screen will appear with the result. The result also will be assigned to a variable named "MatAns". Finally, make sure you have fresh batteries for the HP the day of the exam (unless you are using solar models). If you leave batteries in it for months at a time, the batteries will drain. If you are planning to perform input and display of the calculation result in polar coordinate format, specify the angle unit before starting the calculation.

Display of the calculation result while Linear Display is selected will show a and b i (or r and θ) on separate lines. CMPLX Mode Calculation Examples 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.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 . Many of them such as HP 12C Vs 10bII are mostly used by professionals or students taking accounting courses while the calculator itself can be either using RPN or algebraic system depending on the model. The last and probably more advanced is scientific calculator and as the name suggests, this is the one used when you are studying science, engineering or dealing with math problems due to their collection of functions such as exponents, log, LN, trig functions, and memory that are useful in the application. Using Scientific Calculator Either of two special commands ( r∠ θ or a+ b i) can be input at the end of a calculation to specify the display format of the calculation results.
