Π()
(prodSeq)
Catalog
>
Π(Expr1, Va r, Low, High) ⇒ expression
Note: You can insert this function from the keyboard by typing
prodSeq(...).
Evaluates Expr1 for each value of Var from Low to High, and returns
the product of the results.
Note: See also Product template (Π), page 4.
Π(Expr1, Va r, Low, LowN1) ⇒ 1
Π(Expr1, Va r, Low, High)
⇒ 1/Π(Expr1, Va r, High+1, LowN1) if High < LowN1
The product formulas used are derived from the following reference:

G(Expr1, Va r, Low, High) ⇒ expression
Note: You can insert this function from the keyboard by typing
sumSeq(...).
Evaluates Expr1 for each value of Var from Low to High, and returns
the sum of the results.
Note: See also Sum template, page 4.
G(Expr1, Va r, Low, LowN1) ⇒ 0
G(Expr1, Va r, Low, High)
⇒ MG(Expr1, Va r, High+1, LowN1) if High < LowN1
