Any time while operating the calculator, you can capture an image of the current screen and save it in capture memory.
u To capture a screen image
1. Operate the calculator and display the screen you want to capture.
2. Press !h(CAPTURE). This displays a memory area selection dialog box.
3. Input a value from 1 to 20 and then press w. This will capture the screen image and save it in capture memory area named Capt n (n = the value you input). You cannot capture the screen image of a message indicating that an operation or data communication is in progress. A memory error will occur if there is not enough room in main memory to store the screen capture.

To determine the maximum value for the interval defined by start point a = 0 and end point b = 3, with a precision of n = 6 for the function y = x2 + 2 x + 2
# Inputting a larger value for n increases the precision of the calculation, but it also increases the amount of time required to perform the calculation. # The value you input for the end point of the interval (b) must be greater than the value you input for the start point (a). Otherwise an error occurs. # You can interrupt an ongoing maximum/ minimum calculation by pressing the A key. # You can input an integer in the range of 1 to 9 for the value of n. Using any value outside this range causes an error.

k Arithmetic Operations

[OPTN]-[CPLX]-[i]
Arithmetic operations are the same as those you use for manual calculations. You can even use parentheses and memory. Example 1

All subsequent list operations are applied to the lists contained in the file you select (List File 3 in the above example).
Your graphic calculator can perform the following three types of calculations: Simultaneous linear equations Quadratic and cubic equations Solve calculations
From the Main Menu, enter the EQUA mode.
{SIML}. {linear equation with 2 to 6 unknowns} {POLY}. {degree 2 or 3 equation} {SOLV}. {solve calculation}
Simultaneous Linear Equations Quadratic and Cubic Equations Solve Calculations What to Do When an Error Occurs
4-1-1 Simultaneous Linear Equations
4-1 Simultaneous Linear Equations
You can solve simultaneous linear equations with two to six unknowns. Simultaneous Linear Equation with Two Unknowns:
a1x1 + b1x2 = c1 a2x1 + b2x2 = c2
Simultaneous Linear Equation with Three Unknowns:
1. From the Main Menu, enter the EQUA mode.
2. Select the SIML (simultaneous equation) mode, and specify the number of unknowns (variables). You can specify from 2 to 6 unknowns. 3. Sequentially input the coefficients. The cell that is currently selected for input is highlighted. Each time you input a coefficient, the highlighting shifts in the sequence:
a1 b1 c1 an bn cn (n = 2 to 6)
You can also input fractions and values assigned to variables as coefficients. You can cancel the value you are inputting for the current coefficient by pressing J at any time before you press w to store the coefficient value. This returns to the coefficient to what it was before you input anything. You can then input another value if you want. To change the value of a coefficient that you already stored by pressing w, move the cursor to the coefficient you want to edit. Next, input the value you want to change to. Pressing 3(CLR) clears all coefficients to zero. 4. Solve the equations.
a1x1 + b1x2 + c1x3 = d1 a2x1 + b2x2 + c2x3 = d2 a3x1 + b3x2 + c3x3 = d3

# Internal calculations are performed using a 15digit mantissa, but results are displayed using a 10-digit mantissa and a 2-digit exponent. # Simultaneous linear equations are solved by inverting the matrix containing the coefficients of the equations. For example, the following shows the solution (x1, x2, x3) of a simultaneous linear equation with three unknowns.

To solve the following simultaneous linear equations for x, y, and z 4x + y 2z = 1 x + 6y + 3z = 1 5x + 4y + z = 7
Because of this, precision is reduced as the value of the determinant approaches zero. Also, simultaneous equations with three or more unknowns may take a very long time to solve. # An error occurs if the calculator is unable to find a solution. # After calculation is complete, you can press 1 (REPT), change coefficient values, and then re-calculate.

Differential Calculations

[OPTN]-[CALC]-[d/dx]

To perform differential calculations, first display the function analysis menu, and then input the values using the syntax below. (CALC)* (d/dx) f(x)
(a: point for which you want to determine the derivative, tol: tolerance) d f (a) d/dx ( f (x) a) dx The differentiation for this type of calculation is defined as:
f (a + Ax) f (a) f ' (a) = lim Ax 0 Ax
In this definition, infinitesimal is replaced by a sufficiently small x, with the value in the neighborhood of f' (a) calculated as:

f ' (a)

f (a + Ax) f (a) Ax
In order to provide the best precision possible, this unit employs central difference to perform differential calculations. Example To determine the derivative at point x = 3 for the function y = x3 + 4x2 + x 6, with a tolerance of tol = 1E 5
Input the function f(x). (CALC)* (d/dx) * fx-7400GII: Input point x = a for which you want to determine the derivative. Input the tolerance value. (CALC)
Using Differential Calculation in a Graph Function Omitting the tolerance (tol) value when using the differential command inside of a graph
function simplifies the calculation for drawing the graph. In such a case, precision is sacrificed for the sake of faster drawing. The tolerance value is specified, the graph is drawn with the same precision obtained when you normally perform a differential calculation. You can also omit input of the derivative point by using the following format for the differential graph: Y2=d/dx(Y1). In this case, the value of the X variable is used as the derivative point.
Differential Calculation Precautions In the function f(x), only X can be used as a variable in expressions. Other variables (A through Z excluding X, r, ) are treated as constants, and the value currently assigned to
that variable is applied during the calculation. Input of the tolerance (tol) value and the closing parenthesis can be omitted. If you omit tolerance (tol) value, the calculator automatically uses a value for tol as 1E10. Specify a tolerance (tol) value of 1E14 or greater. An error (Time Out) occurs whenever no solution that satisfies the tolerance value can be obtained. Pressing during calculation of a differential (while the cursor is not shown on the display) interrupts the calculation. 2-24

5. Tests

Test calculations cannot be performed on the fx-7400GII. The Z Test provides a variety of different standardization-based tests. They make it possible to test whether or not a sample accurately represents the population when the standard deviation of a population (such as the entire population of a country) is known from previous tests. Z testing is used for market research and public opinion research, that need to be performed repeatedly. 6-22
1-Sample Z Test tests for the unknown population mean when the population standard deviation is known. 2-Sample Z Test tests the equality of the means of two populations based on independent samples when both population standard deviations are known. 1-Prop Z Test tests for an unknown proportion of successes. 2-Prop Z Test tests to compare the proportion of successes from two populations. The t Test tests the hypothesis when the population standard deviation is unknown. The hypothesis that is the opposite of the hypothesis being proven is called the null hypothesis, while the hypothesis being proved is called the alternative hypothesis. The t Test is normally applied to test the null hypothesis. Then a determination is made whether the null hypothesis or alternative hypothesis will be adopted. 1-Sample t Test tests the hypothesis for a single unknown population mean when the population standard deviation is unknown. 2-Sample t Test compares the population means when the population standard deviations are unknown. LinearReg t Test calculates the strength of the linear association of paired data. With the 2 test, a number of independent groups are provided and a hypothesis is tested relative to the probability of samples being included in each group. The 2 GOF test ( 2 one-way Test) tests whether the observed count of sample data fits a certain distribution. For example, it can be used to determine conformance with normal distribution or binomial distribution. The 2 two-way test creates a cross-tabulation table that structures mainly two qualitative variables (such as Yes and No), and evaluates the independence of the variables. 2-Sample F Test tests the hypothesis for the ratio of sample variances. It could be used, for example, to test the carcinogenic effects of multiple suspected factors such as tobacco use, alcohol, vitamin deficiency, high coffee intake, inactivity, poor living habits, etc. ANOVA tests the hypothesis that the population means of the samples are equal when there are multiple samples. It could be used, for example, to test whether or not different combinations of materials have an effect on the quality and life of a final product. One-Way ANOVA is used when there is one independent variable and one dependent variable. Two-Way ANOVA is used when there are two independent variables and one dependent variable. The following pages explain various statistical calculation methods based on the principles described above. Details concerning statistical principles and terminology can be found in any standard statistics textbook. On the initial STAT mode screen, press the following items.

If you save an eActivity file using a calculator model covered by this manual to save a file with a file name extension g1e (a file transferred from an older version calculator), the file name extension will be determined according to the following rules. The g2e extension is used for an eActivity file that includes data for new features (except for math functions and commands) added by OS Version 2.00 or later. Here, the expression data for new features added by OS Version 2.00 or later means, for example, calculation result data displayed in or format. The g1e extension is used for eActivity files other than those described above.
To replace the existing file with the new version
Press (FILE) (SAVE) to save the currently open file.
1. On the eActivity workspace screen, press This will display a file name input screen. 2. Input up to 8 characters for the file name and then press. If a file already exists with the same file name you enter in step 2, a message will appear asking if you want to replace the existing file with the new one. Press (Yes) to replace the existing file, or (No) to cancel the save operation and return to the file name input dialog box in step 2. (FILE) (SV-AS).
An eActivity file with the g2e file name extension cannot be opened on a calculator running an operating system older than OS Version 2.00. Opening an eActivity file with the g1e filename extension, inputting functions added with OS Version 2.00 or later, and then saving the file may cause the new save to retain the g1e file name extension. Though you will be able to open such a file on a calculator running an operating system older than OS Version 2.00 (since it has the g1e file name extension), you will not be able to use the math functions and commands added since OS Version 2.00.
Displaying the eActivity Memory Usage Screen
The maximum size of an eActivity file is approximately 30,000 bytes.* You can use the eActivity file memory usage screen to check how much memory capacity remains for the file you are currently working on. * Actual maximum file size depends on capture memory and clipboard memory usage, and may be less than 30,000 bytes.
