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, ) 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 first derivative, second derivative, integration, Σ, maximum/minimum value, Solve or RndFix 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.

kΣ Calculations[OPTN]-[CALC]-[Σ(]

To perform Σ calculations, first display the function analysis menu, and then input the values using the syntax below.

<Math input/output mode>

K4(CALC)6(g)3(Σ( ) ak e k e α e β

or

4(MATH)6(g)2(Σ( ) ak e k e α e β

<Linear input/output mode>

K4(CALC)6(g)3(Σ( ) ak , k , α , β , n )

Σ(ak, k, α, β, n) = Σαak =aα + aα +1 +........+ aββk =

(n: distance between partitions)

Example To calculate the following:

Σ6 (k 2 – 3k + 5)

k = 2

Use n = 1 as the distance between partitions.

ΣCalculation Precautions

•The value of the specified variable changes during a Σ 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.
