Σ ( f ( x ), a , b ) = f ( a ) + f ( a + 1) + .... + f ( b ) f ( x ): Function of X (All non-X v ariables are treated as constants.
E-38 • If you perf or m coordinate con version inside of an e xpression instead of a stand-alone operation, the calculation is performed using only the first value (either the r -v alue or the X-value) produced b y the conv ersion.
E-39 Rounding Function (Rnd) This function rounds the value or the result of the e xpression in the function’ s argument to the number of significant digits specified by the number of displa y digits setting. Display Digits Setting: Norm1 or Nor m2 The mantissa is rounded to 10 digits.
E-40 (Check rounded result.) *14= FIX k Practical Examples Appendix <#042> ∫ (sin X + cos X ) 2 dX = π 0 π ( tol : Not specified) <#043> Confirm that the two sides of the f ollowing eq.
E-41 Note •W hen you transf or m from decimal f orm to standard form, the calculator automatically decides the standard form to use. Y ou cannot specify the standard form. Fr action: The current fraction displa y format setting determines whether the result is an improper fraction or mixed fraction.
E-42 Complex Number Calculations (CMPLX) Y our calculator can perform the following comple x number calculations. •A ddition, subtraction, multiplication, division •A rgument and absolute value ca.
