SOURCE: Model FX-85GT PLUS- When dividing

There isn't a problem per se. The calculator is simply showing you the result as an improper fraction.

Press the S--D key to toggle the result between symbolic and decimal forms. To have the results always come up in decimal, press SHIFT [SETUP] 2 to select the LineIO mode.

Press SHIFT then MODE. You can then press 6 to select Fix, followed by the desired number of digits after the decimal point, or press 8 and select one of the two Norm modes.

Full details are on pages E-5 and E-6 of the manual. If you need a manual, you can download it at

SOURCE: HOW CAN I INSERT THE

Same question, same answer.
Sorry, but you cannot.
You can type in a formula that involves the memory variables X,Y, A, B,C,D, E, =, . Such a formula is meant to be evaluated to get a solution (X by default). Once you type the formula you press the Shifted function SOLVE and you will be prompted for the constants, for Y etc. when you press the EXE/= key you get the value of X.
If you turn off the calculator or change the calculation MODE, it is wiped out of memory.

To make a long story short, you cannot STORE formulas in the calculator. Better try to memorize them (commit then to YOUR OWN memory).

If you have the so-called xRoot key you procede as follows; 10[xRoot] 1.797
If you do not have an xRoot key you use the equivalence nth root of x= x to the power of 1/n
In the case of the 10th root you type (1.797)^(1/10) or (1.797)^(0.1). Here the [^] caret is the general power key. On some calculators it is marked as [X^y] or [Y^x]

How to change a decimal value to binary number in fx-85GT PLUS ? Thanks!!


Let's do the preocess so it will work on any calculator.

As an example, convert 68 from decimal to binary.

The decimal columns are 10^0, 10^1, 10^2, 10^3, etc.

The binary columns are 2^0, 2^1, 2^2, 2^3, etc.

Flipping to the normal left to right, we get 2^6, 2^5, 2^4, 2^3, 2^2, 2^1, 2^0.

64 32 16 8 4 2 1

We divide our number, 68, by 64, and get 1 with a remainder of 4. We next divide our remainder by 32, 16, 8, and finally 4, where we get 1 with no reminder.

In binary, this works out to 1000100. To check, we multiply the ones by the respective column values and get 64 + 4 = 68.

Good luck.

Choose 1-Var or any regression model. If you press 1-var you will have two lists x and frequency.
For any regression model you have 3 lists x, y, and Freq(uency).
L1, L2, L3, are list names in the TI 83/84 Plus and the Casio graphing calculators.
I hope it helps

How do you do turn on diagnostics with a casio fx-9750g plus?


You don't do anything for the Casios.. If the correlation and determination coefficients have a meaning in the regression model (such as linear regression) they will be calculated and displayed automatically on the same screen where the regression equation is displayed. However if the regression model has no such coefficients nothing will be displayed.

This is what you see.

8_1_2011_10_35_06_am.jpg
Press F3 to activate the REGression tab.
This is what you will see: the TABs at the bottom of screen.
Each tab corresponds to a regression model: X-linear, X2 quadratic, etc.
8_1_2011_10_38_52_am.jpg
If you press F3:X^2, you get the following
8_1_2011_10_36_07_am.jpg
You see the parameters of the regression equation, the coefficient of determination r^2, and the Mean Square error. No correlation coefficient is defined for this regression model.
For other models like linear, logarithmic, power and exponential regressions, the correlation coefficient is defined and is thus displayed with the regression equation. It is the r-value.
