- Product( <List of Raw Data> )
- Calculates the product of all numbers in the list.
- Example:
Product({2, 5, 8})
yields 80.
- Product( <List of Numbers>, <Number of Elements> )
- Calculates the product of the first n elements in the list.
- Example:
Product({1, 2, 3, 4}, 3)
yields 6.
- Product( <List of Numbers>, <List of Frequencies> )
- Calculates the product of all elements in the list of numbers raised to the value given in the list of frequencies for each one of them.
- Examples:
Product({20, 40, 50, 60}, {4, 3, 2, 1})
yields 1536000000000000Product({sqrt(2), cbrt(3), sqrt(5), cbrt(-7)}, {4, 3, 2, 3})
yields -420
- Note: The two lists must have the same length.
CAS Syntax
- Product( <List of Expressions> )
- Calculates the product of all elements in the list.
- Example:
Product({1, 2, x})
yields 2x.
- Product( <Expression>, <Variable>, <Start Index>, <End Index> )
- Calculates the product of the expressions that are obtained by replacing the given variable with every integer from start to end.
- Example:
Product(x + 1, x, 2, 3)
yields 12.
