Casio fx-9750 calculator please help!!?
By using the stats mode, key in all into the list and select the list by pressing CALC >> SET and set the list and frequency. After that you view the standard deviation by pressing the 1VAR button. The standard deviation will be the one with a lower case sigma. The mean will the the one that has a dash on an X. The variance is simply the sum of all X squares, which is represented by a upper case sigma and followed by X^2.
Unit to Unit File Transmit/Receive problems in CASIO fx-9860G Calculators?
Yeah, I know. Wrong section. But this is one of those high-end, recent model graphing calculators, and nobody in the Consumer Electronics category has answered this same question. So I thought I'd show it to my fellow nerdy astronomers. I have two CASIO fx-9860G calculators, the exact same model. I have the SB-62 3-pin cable that links them. I tried to transmit a program from one calculator to the other, but I got the message TRANSMIT ERROR (PRESS EXIT). I checked the settings. Yes, both calculators are set for 3-pin cable, not for the USB cable. Yes, the receiving calculator was set to receive before the transmitting calculator began transmitting. No, the amount of data to be transmitted should not have even come close to filling up the memory of the receiving calculator. What else might be wrong? I don't understand why the file transmission did not work?
How do I calculate a mod in a scientific calculator (Casio fx-82MS)?
This calculator does not have any modulo function. However there is quite simple way how to compute modulo using display mode ab/c(instead of traditional d/c).How to switch display mode to ab/c:Go to settings (Shift + Mode).Press arrow down (to view more settings).Select ab/c (number 1).Now do your calculation (in comp mode), like 50 / 3 and you will see 16 2/3, thus, mod is 2. Or try 54 / 7 which is 7 5/7 (mod is 5). If you don't see any fraction then the mod is 0 like 50 / 5 = 10 (mod is 0).The remainder fraction is shown in reduced form, so 60 / 8 will result in 7 1/2. Remainder is 1/2 which is 4/8 so mod is 4.EDIT: As @lawal correctly pointed out, this method is a little bit tricky for negative numbers because the sign of the result would be negative.For example -121 / 26 = -4 17/26, thus, mod is -17 which is +9in mod 26. Alternatively you can add the modulo base to the computation for negative numbers: -121 / 26 + 26 = 21 9/26 (mod is 9).EDIT2: As @simpatico pointed out, this method will not work for numbers that are out of calculator's precision. If you want to compute say 200^5 mod 391 then some tricks from algebra are needed. For example, using rule (A * B) mod C = ((A mod C) * B) mod C we can write:200^5 mod 391 = (200^3 * 200^2) mod 391 = ((200^3 mod 391) * 200^2) mod 391 = 98
Engineering: What are some Casio Calculator FX 991MS tricks?
There are so many tricks which will make the fx 991 ms calculator usable as a toy…some of them areAlien transmission techniqueIn alien trick, which is also known as matrix hack method…..the numbers and the symbols in the calculator…will fly automatically..in the screen space…..Shift,on,7Press these keys at same time..press shift again and again.then see the magicTyping using calculatorAll alphabets except v,w,j,q can be typed in calculatorNumber saving methodFx 991 ms calculator can store up to 80 numbers in SD mode…put calculator in SD mode….type any no; press m+ key..type another no; press m+ ..it can be repeated 80 times and so 80 numbers can be stored in calculatorSynchronized typingEg; ram in americaIf this is the sentence…then.The word “Ram “will come first on the screenThen if you press=the word “in” comes nextPress another = the word “ america” will come……Similarly songs lyrics can be displayed.synchronously..on the calculator while playing the musicOther tricks which I knowIntegration with upper and lower limitsDifferentiationMatrix solvingDeterminant transpose etcFinding roots of a polynomialSolving equation in single stepIe ,for eg; 3 sinx - 5=59It can be solved in one stepVector addition

How do you get the critical value of z with a stats calculator?
I'm supposed to find the critical z value for a 97% confidence interval, which should equal to +- 2.17. I will not be given a cumulative standardized normal distribution table for the test so I need to know how to find the value on a calculator. I have a casio fx-9750gii I clicked Distribution --> norm --> InvN I set the tail to central, area to 0.985, I don't know what to set the population standard deviation and population mean.
What are the differences between scientific calculators and graphing calculators?
In the present competitive world, there are many different types of calculators available in the market. Out of these, the two most popular ones are a scientific and graphing calculator. Finding a best scientific calculator or a graphical one can only be possible if you know the basic differences between them.FunctionsA scientific calculator has the capability to perform calculations more than just division, multiplication, subtraction, and addition. You can perform functions, like trig, exponents, and logarithms. On the other hand, you will type a function and see a graph of it in a graphing calculator. In addition, the graphing calculator can solve integral calculus and matrices, which is not possible with a scientific calculator.Screen sizeThe graphing calculator has a larger screen as compared to the scientific calculators so that the users can see the graph of a function accurately if they enter the function. It also makes them a bit more complicated than the scientific ones.CostDo you know there is a huge price difference between these two types of calculators? A scientific calculator costs around $10, whereas the price of graphing calculator starts from $90. It is due to the features and functions that come in the later one. That’s why only professionals go for these costly calculators.Advanced featuresThe graphing calculators are much more advanced than the scientific calculators and that’s why they are more expensive. They are most commonly used in the advanced math classes, whereas the scientific calculators are used by the engineers, architects, and designers.CompatibilityThe graphing calculators are equipped with the Wi-Fi capabilities so that the data from other scientific devices like meteorological gauges, decibel meters, light meters, electronic thermometers, etc. can be evaluated. This type of compatibility isn’t available in the scientific calculators.
