Integration 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, Ƨ) are treated as constants, and the value currently assigned to that variable is applied during the calculation. • Input of "tol" and closing parenthesis can be omitted. If you omit "tol," the calculator automatically uses a default value of 1E-5. • Integration calculations can take a long time to complete. • You cannot use a differential, quadratic differential, integration, 3, maximum/minimum value, Solve, RndFix or logab calculation expression inside of an integration calculation term. • In the Math input/output mode, the tolerance value is fixed at 1E-5 and cannot be changed. I 3 Calculations [OPTN]-[CALC]-[3(] To perform 3 calculations, first display the function analysis menu, and then input the values using the syntax below. *(CALC)* (E)(3( ) ak k A B n (ak, k, , , n) = ak = a + a+1 +........+ a k = (n: distance between partitions) * fx-7400GII: (CALC) Example To calculate the following: 6 (k2 - 3k + 5) k = 2 Use n = 1 as the distance between partitions. *(CALC)*(E)(3( )?(K) V B?(K) D ?(K)AE@U * fx-7400GII: (CALC) 3 Calculation Precautions • The value of the specified variable changes during a 3 calculation. Be sure to keep separate written records of the specified variable values you might need later before you perform the calculation. • You can use only one variable in the function for input sequence ak. • Input integers only for the initial term (A) of sequence ak and last term (B) of sequence ak. • Input of n and the closing parentheses can be omitted. If you omit n, the calculator automatically uses n = 1. • Make sure that the value used as the final term B is greater than the value used as the initial term A. Otherwise, an error will occur. • To interrupt an ongoing 3 calculation (indicated when the cursor is not on the display), press the key. • You cannot use a differential, quadratic differential, integration, 3, maximum/minimum value, Solve, RndFix or logab calculation expression inside of a 3 calculation term. • In the Math input/output mode, the distance between partitions (n) is fixed at 1 and cannot be changed. 2-28
