The calculator then asks SCI 0~9? Thisgives the option of how many digits are displayed. The gives you 10 digits. Notice asmall sci appears in the screen.If you press ×1004whichmeans3.570 × 104. This rounds the number to 4 digits.Practise using the and keys on your calculator8.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.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 × 1ing 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].An M appears in the display when you put something in memory.916–()216---------------------2316–()216------------------------1716–()216------------------------++key to activate M–)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:firstpress 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(sample)(population)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.)On the Casio fx -82MS , σ and s are found in s-V AR. The positions of keys needed are shown on the diagram below.x Σxn-----=σn σn -1input data keyTo find the mean and standard deviation,firstly you must access the statistics mode of the calculator by using the keysfollowed bySD 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 3 such keys on the Casio fx -82MS. Make sure you can locate them. Before starting any computations always clear the statistic’s memories using Scl. PressI will use the data set A (–5, 2, 3, 4, 11) to demonstrate the use of the calculator. Note that I have shown the use of thekey where necessary.Step 1: Input the e theThe display should read n = 5. (This means 5 observations have been input).Step 3: Display the mean and standard deviation.Pressthe display shows three alternativesPressx σn = 5.099019514Pressx σn –1 = 5.700877126ExampleUse 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:The mean is 3, the standard deviation is 13.87 and the variance is 192.5. button accesses a number of extra statistical functions.If you have made an error with inputting your data you can correct it by using the up and down key.For example, you inputreads x 3 = 60, then pressIn the example below, the progressive calculations are shown simply to give you someunderstanding of the underlying processes – you should do one or two examples in detail and then check them by calculator.=Σx 2 =815=Σx = 15=n= 510.2 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.

Their lengths and skin thicknesses were measured. Below is a summary of the results.STEPS1.(1 = Linear Regression; there are 5 other types)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 bananaBanana 12345678910Length (mm)16.215.816.514.916.916.815.615.615.715.4Thickness (mm)1.11.21.11.00.91.21.11.20.90.8accesses the keys with ⎡ ⎤ in blueFor each banana you have to put in both numbers.To put in the first set of numbers, press the following keys:is used for the 2nd variableContinue in this mannerAfter you have input all the numbers.The display should read n = 10To find the linear regression equation in the formy = a + b xPressPress∴There 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 the mean thickness (1.055mm) or the standard deviation (0.64mm).x σy σn –1:12.Trigonometric functionsThe keys involved are:Important : Make sure that your calculator is in the correct mode. For example, if your calculator has R or G on the display and you wish to work in degrees, press mode twice and then select 1 for degrees. Your screen should now display D.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 xcm, useThe keystrokes on the calculator are:Example 2In the right-angled triangle below, the length of the hypotenuse 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 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 the 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, .

卡西欧计算器fx-82ES、fx-82ES_Plus系列列方程的方法(键盘操作)
卡西欧计算器fx-82ES、fx-82ES Plus系列列方程的方法（键盘操作）方法一：软升级至fx-991ES（仅适用于fx-82ES）1.shift2.(Pol)3.14.shift5.(,)6.17.)8.=9.狂按分数线，直到按到顶不动为止（似乎是6个）10.按= （显示Syntax ERROR 不要管它），AC，左11.112.幂（在方向键下面，就是X上面有个小白框的键）13.=14.AC15.向上键16.AC17.向左键三次18.DEL19.根号Ans20.=21、十个Ans22、两个log■□23.右右右，按“（”按到乱码涨上来，大概10个24.=右，左左按“sin（”按到乱码涨上来，大概7个25.=右，左，按7个“（”不停重复25步......直到屏幕上的乱点消失，光标不见26.AC27.shift+9+128.升级成功，请修复后用线性模式按mode出现8个，可以自由转换，EQN也可以用了，最大缺陷是在数学模式下计算就死机。
注：EQN模式就是方程模式。
方法二：升级至牛顿解方程功能（仅适用于fx-82ES）1.打出r（正常模式下，具体方法看上面）2.r前一分之一3.M+4.出现错误，别管他按AC5.5个分数线6.=7.ac8.←9.+10.111.幂（会变为线性格式）12.=13.ac14.1÷215.shift+9+1 + = + =alpha+abs是=shift+abs是解方程方法三、利用START模式（适用于fx-82ES、fx-82ES Plus系列）很多人说fx-82ES PLUS不能解方程，其实并非如此，它可以解一部分方程，但过程有些麻烦，不如95和991的EQN好用。
82ES PLUS可以解下列方程1、一元一次方程2、一元二次方程3、二元一次方程组4、少数分式方程5、比例式首先按MODE，按2(STAT)。
一元一次方程(说例统计表中，第一行X和Y都是0(只需要在X列按一下0和=就行了)，第二行X列输入a的值(这里是8)，Y列打出c-b的值(这里打21-5或打16都行)，按AC，按SHIFT，按1，按5(Reg)，按2(B)，按等号，显示的值就是方程的解了。
