- Sequence[Expression, Variable i, Number a, Number b]
- Yields a list of objects created using the given expression and the index i that ranges from number a to number b.
Example:
L = Sequence[(2, i), i, 1, 5] creates a list of points whose y-coordinates range from 1 to 5: L = {(2, 1), (2, 2), (2, 3), (2, 4), (2, 5)}.
- Sequence[Expression, Variable i, Number a, Number b, Increment]
- Yields a list of objects created using the given expression and the index i that ranges from number a to number b with given increment.
Example:
L = Sequence[(2, i), i, 1, 3, 0.5] creates a list of points whose y-coordinates range from 1 to 3 with an increment of 0.5: L = {(2, 1), (2, 1.5), (2, 2), (2, 2.5), (2, 3)}. Note: Since the parameters a and b are dynamic you could use slider variables in both cases above as well.
- Sequence[<Number b>]
- Creates list of numbers 1 to b, e.g. {1,2,...,b}.
Example:
L = 2^Sequence[4] creates list {2,4,8,16}. See Lists for more information on list operations.
