*1 A base of 10 (common logarithm) is used if no base is specified.
kPower Functions and Power RootFunctions
•Power functions and power root functions can be used in the COMP, STAT, EQN, MATRIX, TABLE, and VECTOR calculation modes.
•The X2, X3,
•The X^, '(, 3'(, ^'( functions can be used in the CMPLX Mode, as long as complex numbers are not used as their arguments.

kIntegration CalculationsThis calculator performs integration using the
∫( f(x), a, b, tol)
f(x): Function of X (All
a: Integration interval lower limit
b: Integration interval upper limit
tol: Tolerance range (input/output format: Linear)
•You can omit specification of the tolerance range. A default value of 1 ⋅
•∫(, d/dx(, Pol(, Rec(, and Σ( cannot be used within f(x), a, b, or tol.
•Integration calculations can be performed in the COMP Mode only.
•The integration result will be negative when f(x) < 0 within an
integration interval that conforms with a <x <b. Example: ∫(0.5X2 – 2,
•A “Time Out” error occurs when an integration calculation ends without the ending condition being fulfilled.
•When performing an integration calculation involving trigonometric functions, specify Rad as the calculator’s default angle unit.
•Integration calculations can take considerable time to complete.
•A smaller tol value provides better precision, but it also causes the calculation to take more time. Specify a tol value that is 1 ⋅
•You cannot input a tol value when using Math format.
•There may be large error in obtained integration values and errors may occur due to the type of function being integrated, the presence of positive and negative values in the integration interval, or the interval.
•Pressing Awill interrupt an ongoing integration calculation.
