∫() (integral)
Catalog >
∫(Expr1, Var, Lower,Upper) ⇒ value
Returns the integral of Expr1 with respect
to the variable Var from Lower to Upper.
Can be used to calculate the definite
integral numerically, using the same
method as nInt().
Note: You can insert this function from the
keyboard by typing integral(...).
Note: See also nInt(), page 101, and
Definiteintegral template, page 6.
√() (square root)
/q keys
√(Value1) ⇒ value
√(List1) ⇒ list
Returns the square root of the argument.
For a list, returns the square roots of all the
elements in List1.
Note: You can insert this function from the
keyboard by typing sqrt(...)
Note: See also Square root template, page
1.
Π() (prodSeq)
Catalog >
Π(Expr1, Var, 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
5.
Π(Expr1, Var, Low, Low−1) ⇒ 1
Π(Expr1, Var, Low, High) ⇒ 1/Π(Expr1,
Var, High+1, Low−1) if High < Low−1
