  • Input integers only for the initial term ( 
α 
) of sequence a k  and last term ( 
β 
) of sequence a k .
  • 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 
β 
 is greater than the value used as the initial 
term 
α 
. Otherwise, an error will occur.
  • To interrupt an ongoing Σ  calculation (indicated when the cursor is not on the display), press 
the A key.
  • You cannot use a first derivative, second derivative, integration, Σ , maximum/minimum value, 
Solve or RndFix calculation expression inside of a Σ  calculation term.
  • In the Math input/output mode, the distance between partitions ( 
n ) is fixed at 1 and cannot be 
changed.
k Maximum/Minimum Value Calculations   [OPTN]  -  [CALC]  -  [FMin]/[FMax] 
  After displaying the function analysis menu, you can input maximum/minimum calculations 
using the formats below, and solve for the maximum and minimum of a function within interval 
a  < x  < b . 
u Minimum Value
K4(CALC)  6( g) 1(FMin) f 
( x ) , a  , b  , n  )
   ( 
a : start point of interval, b : end point of interval, n : precision ( n  = 1 to 9))
u Maximum Value
K4(CALC)  6( g) 2(FMax) f 
( x ) , a  , b  , n  )
   ( 
a : start point of interval, b : end point of interval, n : precision ( n  = 1 to 9))
  Example  To determine the minimum 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  = x 
2 
 – 4 x  + 9
  Input 
f 
( x ).
       AK4(CALC)  6( g) 1(FMin) vx-ev+j,  
  Input the interval a  = 0, b  = 3.
       a,d,
  Input the precision n  = 6.

• 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.
