Find theon your calculator. To get tothis key you must press shift first.Look at the examples below.727210222264121225Examples(a)9½and the display should read 3.orand the display should read 3.(b)and the display should read 2.(c)16¼and the display should read 2.Note:•Root key is a function at the back of the power key, so you will need to activate it with theSHIFT key•See the key . The x stands for the root you want to take so it is typed first.•From the examples above you may have seen that . is called a fractionalindex.813--x 813--83=813--5.FractionsHow do you add and ? Normally you would have to find a common denominator of 252.So:Or you can use your calculator to add fractions. Find thekey On the key the ‘a ’ represents the whole part of a mixed number and the ‘’ represents the fraction part of a mixed number.When the number you are typing is a proper or improper fraction the ‘a ’ is zero and there is no need to type a value for it.The key storkes required for the calculation are:and the display will show 37 ⎦ 252 which is read as 112-----463-----112-----463-----+21252--------16252--------+37252--------==a b c--fraction keya b c --b c--112-----463-----+37252--------Example Find Using the calculator the key strokes are:and the display will show 8 ⎦ 71 ⎦ 72 which is read as Note if you now press. So this key turns a mixedfraction into an improper fraction.If you press the key a second time the decimal equivalent is displayed,i.e. 8.98611116.Using the 1/x key819--6372-----+87172-----64772--------ExampleLook at this simple example is the same as You can input this in your calculator by pressingThe answer should be 0.571428571. This would be the same as if you just typed 4 ÷ 7Take another example Type:The answer should be 0.05194805147--417--×483+()7×-------------------------7.Scientific notationSometimes you may have numbers expressed in scientific notation, i.e., 7.24 × 103 instead of 7240. When a number is multiplied by 103right. You can do this on the calculator by using the key.PressIf you want to multiply two numbers e.g. 8.34 × 10–2 × 4.28 × 105. Pressand the display will read 35695.2If you press 04 which means 3.56952 × 104. Pressing the mode three times gives you the displayThegives the option of how many digits are displayed. Thesmall sci appears in the screen.If you press 04 which means 3.570 × 104. This rounds the number to 4 digits.Practise using the and8.Factorial x !Look at your calculator and find the key with the symbol x ! on it. You will come across this symbol when doing the Binomial Distribution. This is called the factorial key.Use it to find the 3! and 5!. Press 3! means 3 × 2 × 1 and 5! = 5 × 4 × 3 × 2 × 13! = 65! = 120How many ways would you guess that we could arrange ten people?That is, how large would you estimate 10! to be? Use your calculator to find 10!You should get 3 628 800.10! = 10 × 9 × 8 × ... × 3 × 2 × 1(Thank goodness this can be done on the calculator.)Factorial ruleThe number of ways of arranging n items in order is known as ‘factorial n ’ which is symbolised as n ! where:n ! = n × (n – 1) × (n – 2) ×... × 3 × 2 ×19.Using memoryTo calculate the following it may be useful to use the memory key for each term:Example:To make sure memory is clear, first pressorand make sure you are in normal calculation mode [may need to press mode 1].A small m appears in the display when you put something in memory.916–()216---------------------2316–()216------------------------1716–()216------------------------++To do the calculation above, press the following keys- this puts the first term (3.0625) into the memory then press- this adds the second term (3.0625) into memory then press- this adds the third term 0.0625 to memory.To find the answer press The answer should be 6.1875.Example 2calculate the following:firstto clear the memory thenpress the following keys:your answer should be 11.39917438(There are other memory keys in your calculator – the A to F keys, accessed by using SHIFTSTO and RCL – try them yourselves.)1817---------1717---------1217---------++10.Statistics10.1 Mean and standard deviation – single dataThe formula for the mean is The formulas for the sample standard deviation are(Theoretical formula)(Working formula)Your calculator will calculate the mean and standard deviation for you (the populationstandard deviation or the sample standard deviation – in data calculations you will usually use the sample standard deviation.)The differentiation between σ and s varies with different calculators. On the Casio fx -100 s, σ is denoted by σn and s is denoted by . The positions of these keys is shown on the diagram below.x Σxn-----=s Σx i x –()2n 1–-----------------------=s Σx i 2Σx i ()2n ⁄–n 1–--------------------------------------=σn σn -1σn-1input data keyTo find the mean and standard deviation,firstly you must access the statistics mode of the calculator by using the keysby SD will appear in the centre of the screen.Note that once you are in the statistics mode, the keys shown within the blue lines are active. There are 14 such keys on the Casio fx-100s. Make sure you can locate them. Before startingany computations always clear the statistic’s memories using Mcl. PressI will use the data set A (–5, 2, 3, 4, 11) to demonstrate the use of the calculator. Note that IStep 1: Input the observations.Use the key to input data (no need to press ).Step 2: Check that the correct number of observations have been inputted. [Note this is shown on the inside cover of your calculator under statistical data.]PressThe display should read 5.Step 3: Display the meanand the display should read 3Step 4: Display the standard deviation (assume the data set is a sample)and the display should read 5.7008771__________________________________________________________________________ExampleUse your calculator to find the mean, standard deviation and variance for data set B: –18, 1, 3, 9, 20.(the variance is the square of the standard deviation)__________________________________________________________________________ After you are in the statistics mode and cleared the statistics memories, the keystrokes required are:and the display will read 5and the display will read 3and the display will read 13.87443693The mean is 3, the standard deviation is 13.87 and the variance is 192.5.= Σx2 = Σy2= Σx = Σy= n = ΣxyIn the example below, the progressive calculations are shown simply to give you some understanding of the underlying processes – you should do one or two examples in detail and then check them by calculator.10.2 Mean and standard deviation of frequency distributionGiven below is the frequency table for the weights (kg) of a random sample of 30 first year university female students. Find the standard deviation, the variance and the mean.The calculations needed to obtain the standard deviation without statistical keys for these data are:Σx 2 = 602 × 2 + 612 × 14 + 622 × 8 + 632 + 642 × 5 = 114 495Σx = 60 × 2 + 61 × 14 + 62 × 8 + 63 + 64 × 5 = 1 853s = = Thus:s= 1.2 kg and s 2 = 1.4 kg 2= Note: In calculations like the above you should carry as many decimals as possible until thefinal result. The number of decimals to be retained at the end depends on the accuracy of the data values – one rule of thumb is to have one more decimal than in the original data.Notice how the frequencies were used in the above calculation.The calculator usage now has a small modification because we have been given the frequencies for the variable values. (There is no need to input each single observation.)Graduate’s weight(kg)FrequencyCumulative frequency6022611416628246312564530Σx i 2Σx i ()2n ⁄–n 1–--------------------------------------114 495 1 853()230⁄–29-------------------------------------------------------114 495114 453.6333–29--------------------------------------------------------- 1.4264==x Σx n -----185330-----------61.8 kg==The keystrokes required are:and the display should read 30and the display should read 61.766667and the display should read 1.1943353Thus, as expecteds = 1.2 kg,s 2 = 1.4 kg 2 and = 61.8 kg Exercise 6Find the mean, standard deviation and variance of (a)The annual rainfall data for the years 1971 – 1990Year 1971197219731974197519761977197819791980Rain (mm) 1 3409901 1201 7362601 1001 3791 1251 4301 446Year 1981198219831984198519861987198819891990Rain (mm)1 4591 6781 3459781 0021 1101 5461 6721 4671 123x(b)The sample of snail foot lengthsAnswers:(a)Rainfall statisticsmean:µ = 1 265.3 mm standard deviation:= 336.4 mm variance:σ2 = 113141.7 mm2 (b)Snail statistics mean:= 3.4 cm standard deviation:s = 0.70 cm variance:s2 = 0.49 cm2Snail foot length (cm)2.2 4.13.54.5 3.2 3.7 3.0 2.63.4 1.6 3.1 3.3 3.8 3.14.7 3.72.5 4.33.4 3.6 2.9 3.3 3.9 3.13.3 3.1 3.74.4 3.2 4.1 1.9 3.44.7 3.8 3.2 2.6 3.9 3.0 4.2 3.5σn-1x11.Linear regressionExampleSuppose we had a sample of 10 of the same type of banana. Their lengths and skin thicknesses were measured. Below is a summary of the results.STEPS1.2.Think of the sample of bananas as having two variables–let x be the variable length of banana –let y be the variable thickness of bananaFor each banana you have to put in both numbers.Banana 12345678910Length (mm)16.215.816.514.916.916.815.615.615.715.4Thickness (mm)1.11.21.11.00.91.21.11.20.90.8⎡ ⎤ in bluekey is used to access other statistical dataTo put in the first set of numbers, press the following keys:is used for the 1st variableis used for the 2nd variableContinue in this mannerAfter you have input all the numbers, check to see you have 10 samples.To find the linear regression equation in the formy = a + b xyou need to find the value of a and b. These keys are formed as A and B under the andkeys. The button is used for all buttons with a blue ⎡⎤symbol under it.Press a is 0.3651Press b is 0.0430∴the equation is y = 0.3651 + 0.0430xTo find the correlation coefficient pressr = 0.1928There is not a high correlation between the thickness of bananas and the length of bananas tested.The calculator will also give you other statistics about this sample. Use to get themean thickness (1.055mm) or use to get the standard deviation (0.64mm) or use∑x (sum of all lengths = 159.4mm).to predict the length, given the thickness. If 0.6 is thethickness then pressSimilarly, if the length is 12mm then press to get 0.88 mm as the predicted thickness.12.Trigonometric functionsThe keys involved are:Important: Make sure that your calculator is in the correct mode. For example, if your calculator has RAD or GRAD on the display and you wish to work in degrees, press mode twice and then select 1. Your screen should now display DEG.Example 1In the right-angled triangle below, the length of the side opposite the 20° angle needs to be calculated.To find the length of the side labelled x cm, use The keystrokes on the calculator are:The display should read 1.819851171, so the length of xis about 1.8 cm.Example 2In the right-angled triangle below, the length of the hypotenuse needs to be calculated. To find the length of the side labelled xcm, use:The keystrokes on the calculator are:The display should read 20.466631, so the length of the hypotenuse is about 20.5 cm.Example 3Given the lengths of two of the sides in the right-angled triangle below, find the value of the angle θin degrees:To find the value of θ, you need to use the cos–1 key. The calculator keystrokes are:Note: You must first get the value of the division by using brackets.Your display should read 60°. If it does not, check that you are in degree mode.13.Exponential and logarithmic functionsThere are two log keys on your calculator, with their associated exponential keys. The latter are accessed by first using the shift key:The ‘log’ key uses base 10 and the ‘ln’ key uses base e (natural logarithm).Example 1Solve equation Taking logs of both sides;To find the value of a , the keystrokes are:The display should read 4.3219281.So,2a 20=4.32220≈Example 2Given , find the value of y The key is above the log key. Hence the keystrokes are:The display should read 38.370725Example 3 (harder)Given , find the value of xTo find log x , the calculator keystrokes are:The display should read 0.5187675.Since this is the value of log x , you still need to find xwhere Without removing the answer of 0.5187675 on your display, press:Your display should now read 3.3019272Note: You could use the ‘ln’ key instead of the ‘log’ key – the answer would still be the same.

卡西欧fx系列电子计算器全型号使用说明书

是一个FX-82ES计算机，按下MODE键会显示出三个功能。

同时按下SHIFT-7-ON键（此功能用于出厂测试计算器，嘿嘿），并连按多次SHIFT后，会出现如（图二）所显示的内容。

其中P3便代表FX-82ES的模式，现在我们就要将其修改为FX-991ES的模式。

图(二)图(三)关闭计算器，拆开计算器，可以看到如（图三）的电路板。

找到P4引脚，可以看到当中有条裂缝，用指甲将上面的（尤其是裂缝中的）氧化层刮去，随后用软性铅笔（如2B）在裂缝上涂满，确保裂缝中有足够的碳粉可以导通P4引脚后。

打开计算器，按下MODE，可以看到如图(四)的画面,变成8种模式功能，原来只有3种）这说明你的计算器改装成功了。

图(四)同时按下SHIFT-7-ON键，并连按多次SHIFT后，可以看到如（图五）的画面，P?说明你的计算器连接了两个P引脚，变得十分怪胎了，不过这并不影响使用。

其实，P引脚是用来设置计算机型号的。

卡西欧公司从成本上考虑，将一些计算器使用相同的电路板，只是通过P来设置型号。

可以看到FX-82ES计算器的P3引脚是连通的，而其它的引脚都有一条裂缝。

如果你有兴趣，可以尝试连通其它的，会出现不同的功能，不过连接P4后的功能是最多的，与FX-991ES的功能完全一样。

（如果错了，橡皮擦擦了就好了）改装后的计算器有部分按键与原计算器不同，这里提供了对照表（图六）希望注意。

附：1.卡西欧FX-991ES说明书下载地址：/CALC/DOWNLOAD/CN/MANUAL/2.卡西欧FX-82ES大家可以去本地的文具批发市场和是小一些的商场，和是网络商店，你可以去里面逛逛，一般批发价为48元，零售价为55元左右（如果是大商场80多）。

而FX-991ES的价格为120-160元之间（如果是大商场300多）3.考研规定FX-911ES计算机是肯定能用的，FX-82ES是更不用说了。

所以改装的FX-82ES考研不管能不能用，自己用都是最不错的选择。
