If the roots are complex (in the form of a bi ±), a bi + will be displayed. Hit the down arrow to see the second root. Enter the value for b (the coefficient of x). Enter the value for a (the coefficient of x 2). Solving 2 nd or 3 rd Degree Polynomials Steps to find the roots to a polynomial. Test Masters takes no responsibility on how the calculator is used on the exam. This document was compiled only to assist you in learning your calculator while preparing for the EIT/FE exam. However, we strongly recommend testing out all these functions using your calculator before the actual exam to ensure you know how to enter the data into your calculator correctly and verify the correct answer is given. Independent memory contents and values assigned to variables to be cleared.We have compiled some important functions that are needed for the EIT, and have shown below how to perform them on your calculator. Removing the button batter y from the calculator causes.Even if the calculator is operating normally, replace the battery at least once every three years. When any of these symptoms occur, replace the button battery. Note that you will not be able to use the calculator if its button battery is dead. The TWO WAY POWER system, however, lets you continue to use the calculator as long as there is enough light to read the display.ĭim display figures when available lighting is dim or failure of anything to appear on the display immediately when you turn on the calculator indicates that button battery power is low. Normally, calculators equipped with a solar cell alone can operate only when relatively bright light is present. Your calculator uses a TWO WAY POWER system that combines a solar cell with G13 type button battery (LR44). (4) Initialize all modes and settings by performing the following operation: For details about initialized settings, see “Initializing the Calculation ModeĪnd Other Settings” under “Calculation Modes and Calculator Setup”. If the calculator discovers any abnormality, it automatically initializes the calculation mode and clears memory contents. This willĬause the calculator to perform a routine that checks whether calculation functions are operating correctly. (3) If the above steps do not correct your problem, press the O key. (2) Make sure that you are using the correct mode for the type of calculation you (1) Check the calculation expression to make sure that it does not contain any Note that you should make separate copies of important data before performing these steps. If one step does not correct the problem, move on to the next step. Perform the following steps whenever an error occurs during a calculation or when calculation results are not what you expected. K Before assuming malfunction of the calculator.
