About this deal

These calculators are fairly the same and what makes them attractive is the price range in which they are also identical to each other. Performance wise the FX 991EX has better display and faster processor so it can give the result faster as well, including how it adds some useful upgrades for example in the equation mode but on the downside, it has smaller fonts and some functions that may be useful to you are missing. Name You can choose FX-991 instead of simple FX-991 for much better ergonomics, enhanced and contrasting button colors, and better-built quality. You can avoid mistakenly hitting the wrong buttons in a hurry with improved ergonomics and better color adoption. The HP35S is by far the best, complex numbers, solve, rpn make this calculator the best for engineer. No doubt. However, the button layout of these calculators are identical, you will find a certain button at the same place but now with a different shape. They still have these shift buttons and alpha buttons on the top left which should be pressed whenever you want to access the function stated in the same color.

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.All the calculator optionshandlematrix operations, linear systems of equations, interpolation, and numerically solve definitederivatives and integrals To ensure the integrity of FE exams, NCEES® restricts your calculator choice by strictly directing you to choose FE approved calculators. The list of NCEES® approved calculators is revised each year by NCEES® that includes the most appropriate and best calculators for the FE exam. You are strictly obliged to use calculators approved by NCEES®.

The following functions cannot be input in consecutive sequence: x 2, x 3, , x -1. If you input 2 , for example, the final will be ignored. To input 2 2 2,input 2 , press the key, and then press (MthIO-MathO). Example 5: For the single variable data { x n; freq n} = {0;1, 1;2, 2;1, 3;2, 4;2, 5;2, 6;3, 7;4, 9;2, 10;1}, to determine the normalized variate ( t) when x = 3, and P( t) at that point up to three decimal places (Fix 3). 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. There are many Casio fx-115 models but you will be hard-pressed to find any other than the ES Plus. Some have been discontinued, and some are simply impossible to find for sale. Both of the TI’s (the 30X and 36X) are still on the market and readily available. The 36X is a little more money because it has a much better display screen. Many engineering graduates know how to use TI-89s and TI-90s. They are comfortable with the navigational layout of TI’s menu system.For details see "Commands when Linear Regression Calculation (A+BX) Is Selected" and "Commands when Quadratic Regression Calculation (_+CX 2) Is Selected".

Pressing the key while the Statistics Editor is displayed switches to the Statistics Calculation Screen. 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. Move the cursor to the cell that contains the element you want to change, input the new value, and then press . This will display the Matrix Editor for input of the elements of the 2 × 2 matrix you specified for MatA.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. 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. Many engineering graduates know how to use TI-89s and TI-90s. They are comfortable with the navigational layout of TI's menu system. Most of us barely scratch the surface of what our calculators are capable of, even with the simpler scientific calculators. Take some time to get out your user manual and find out what you can do. If you don’t have a user manual, don’t worry: you can find them on the web fairly easily.
