Casio FX 83 ES Calculator

Product Information

The value stored in the ‘M’ memory can also be changed by adding or subtracting the result of a further calculation: we can see that no matter what the values of and , the formula always requires the value of . If we wished to calculate the volume of wood contained in several different logs, it might be efficient to calculate the value of once, store it in memory and reuse this value in the subsequent calculations. Note that when entering this expression in your calculator, it is possible to omit explicitly entering the multiplication between the 2 and since the calculator will assume it. If you are using a different model of calculator, make sure that you can identify similar functions on your model. The first step in using your calculator effectively is to make sure that you are familiar with the layout of the keys on the keypad, and that you can understand the information on the display.

The value of (which equals 0.0796 to 3 significant figures) can be calculated using and stored in the ‘M’ memory using the key sequence (STO) (M). To initialise your calculator to the default course settings, turn it on and then enter the following two key sequences: Your calculator can be set to calculate trigonometric functions using the radian measure for angles, instead of degrees, by using the key sequence (SETUP) (Rad). Set answers to be displayed in scientific notation with 3 significant figures (To use a different number of significant figures, replace with that number)

If you obtained the answer or 0.5236 (to 4 decimal places), then your calculator is set to work in radians. Make sure that you are working in degrees. If a severe error is made when entering a calculation into the calculator, it may prevent the answer being calculated at all, as the calculation may not make mathematical sense. In such circumstances a ‘Syntax Error’ will be displayed as shown in Figure 6. The Syntax Error screen gives you two options: An alternative approach to our calculation is to calculate the denominator of the fraction first, and then divide the numerator by this. It is possible to set the calculator so that answers that are top-heavy fractions (such as ) are always displayed as mixed numbers (such as ).

Once (or (STO)) has been pressed, the display indicator RCL (or STO) is shown on the display to indicate that the calculator is waiting to know which memory to recall (store) the value from (in). Normal 1 (Norm 1) mode uses scientific notation for any number less than 0.01 but greater than −0.01, and otherwise displays answers to however decimal places they have, subject to the maximum that will fit on the display. This mode is entered using (SETUP) (Norm) . to 3 significant figures). If you got 0.657, then your calculator is currently set to calculate in radians, so reset it to work in degrees using (SETUP) (Deg). Normal 2 (Norm 2) mode uses scientific notation for any number less than 0.000000001 but greater than −0.000000001, but otherwise displays answers to however many decimal places they have, subject to the maximum that will fit on the display. This mode is entered using (SETUP) (Norm) .

There are several keys on the calculator that enable you to perform calculations involving powers. For small powers such as squares or cubes there are dedicated buttons, and , which are located in the function key area of the keypad. These are used in a similar manner to how you would write mathematics; for example, to enter you would press . The display also shows the maths in the same way as you would write it on paper.A variation on the above method is to break the calculation into two parts, and use the memory functions of the calculator to store the result of the first part. The calculator memory is particularly useful when you want to calculate the values of several expressions that have a common part. This common part need be entered only once and its value reused several times subsequently. For example, rewriting the formula for the volume of wood contained in a log as Math Error’, when the calculation you entered makes mathematical sense but the result cannot be calculated, such as attempting to divide by zero, or when the result is too large for the calculator to handle. Sometimes when entering into your calculator an expression involving roots, you may accidentally forget to press the appropriate function key. However, moving the cursor to the correct point and pressing the missing key, as in section 1, will not work as this simply inserts an empty template.

There is more information available than can be displayed, and this can be accessed using the up/down cursor keys.

The volume of wood (in cubic metres) contained in a log of length metres with a distance around its middle of metres is given by the formula In some circumstances, however, it may be easiest to abandon what you have typed and start again, by pressing the ‘all clear’ key! The calculator has several different memories. We shall first consider the ‘M’ memory, which is accessed using the key (and its associated functions) at the bottom right-hand corner of the function key area. You know that you are in Math mode if the word Math is shown near the right-hand side of the top of the calculator display. If this is not shown, you are using Linear mode.In this section we consider several different approaches that can be used to evaluate this and other more complex expressions using different functions on your calculator. While the first method – considered in Activity 9 – is probably the most straightforward for this relatively simple expression, it is useful to see how you might use other calculator functions when you are faced with more complicated expressions to evaluate. Note that in the first key sequence, ‘CLR’ (which is short for ‘clear’) is the second function of the key, and ‘Setup’ is the name of the on-screen menu option corresponding to the key. ‘Yes’ is the name of the on-screen menu option corresponding to the key. This key sequence clears all previous ‘setup’ settings on the calculator. The first 11 sections describe how to use the calculator and how to perform different types of calculations. Section 12 contains a calculator reference guide that you can refer to as needed for some of the main key sequences. Remember, your calculator is in Math mode if the word Math is shown at the top of the calculator display. If your calculator is not in Math mode, repeat the steps of Activity 1. In Activity 1 you will have already set your calculator to use Norm 2 mode, and we suggest that for the moment you continue to use this. To change the mode, use the key sequence (SETUP) (Norm) followed by (for Norm 1) or (for Norm 2).
