Most of us hardly skim the surface of what our devices are capable of, whether they are smartphones or calculators. In general there are basic calculators, business or finance calculators, and scientific calculators which are usually the most expensive and most complicated to use. 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. If you decide you want to use a specialized command or function, don’t wait until the night before the test to try it out. 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 .

Calculators are obviously an important part of the FE exam and make a big difference in the time spent per question. You can learn more about this best calculator for the FE exam in our detailed blog related to TI-36X Pro tips and tricks. The fx-115ES Plus 2 is an advanced scientific calculator featuring Natural Textbook Display™ that is an excellent choice for high school and college students learning Algebra II, Trigonometry, Statistics, Calculus, Engineering, and Physics. All data currently input in the Statistics Editor is deleted whenever you exit the STAT Mode, switch between the single-variable and a paired-variable statistical calculation type, or change the Stat Format setting on the setup menu. Lastly, I encourage you to ask questions in the comments of the videos or here on this page and I’ll read and respond to them in future videos.

The TI calculator holds your answer and calculation history if you shift between the different modes. 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. The calculation screen will show the MatAns variable followed by the operator or function for the key you pressed. 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 content to the Statistics Menu depends on whether the currently selected statistical operation type uses a single variable or paired variables.

Regression coefficient, correlation coefficient, and estimated value calculations can take considerable time when there are a large number of data items. 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). When you want to change the calculation type after entering the STAT Mode, perform the key operation (STAT/DIST) (Type) to display the calculation type selection screen. To ensure the integrity of FE exams, NCEES® restricts your calculator choice by strictly directing you to choose FE approved calculators.Finally, make sure you have fresh batteries for the HP the day of the exam (unless you are using solar models). While some problems may be of the “plug and chug” variety, you still have to plug in all those numbers.
