Casio 3.04 SsumSeq, Ssequence

2-8-30

Using the Action Menu

Ssequence

Function: Returns the lowest-degree polynomial that represents the sequence expressed by the input list. When there are two lists, this command returns a polynomial that maps each element in the first list to its corresponding element in the second list.

Syntax: sequence (List-1[, List-2] [,variable] [ ) ]

• “x” is the default when you omit “[,variable]”.

Example: To determine a polynomial for a sequence expressed by the list {3, 5, 7, 9}

Menu Item: [Action][List-Calculation][sequence]

Example: To determine a polynomial that maps each element in the list {1, 3, 5, 7} to its corresponding element in the list {0, –1, 2, –3}.

SsumSeq

Function: Finds the lowest-degree polynomial that represents the sequence expressed by the input list and returns the sum of the polynomial. When there are two lists, this command returns a polynomial that maps each element in the first list to its corresponding element in the second list, and returns the sum of the polynomial.

Syntax: sumSeq (List-1[, List-2] [,variable] [ ) ]

• “x” is the default when you omit “[,variable]”.

Example: To determine the sum of a polynomial for a sequence expressed by the list {3, 5, 7, 9}

Menu Item: [Action][List-Calculation][sumSeq]

Example: To obtain the polynomial that maps the elements in the list {9, 7, 4, 1} to its corresponding elements in the list {0, 4, 6, 5}, and return the sum of the polynomial.
