- Length[Vector]
- Yields the length of the vector.
- Length[Point A]
- Yields the length of the position vector of the given point .
- Length[Function, Number x1, Number x2]
- Yields the length of the function graph in the interval [x1, x2].
- Length[Function, Point A, Point B]
- Yields the length of the function graph between the two points A and B.
- Note: If the given points do not lie on the function graph, their x‐coordinates are used to determine the interval.
- Length[Curve, Number t1, Number t2]
- Yields the length of the curve between the parameter values t1 and t2.
- Length[Curve c, Point A, Point B]
- Yields the length of curve c between two points A and B that lie on the curve.
- Length[List]
- Yields the length of the list, which is the number of elements in the list.
- Length[Text]
- Yields the number of characters in the text.
- Length[Locus]
- Returns the number of points that the given locus is made up of. Use Perimeter[Locus] to get the length of the locus itself.
Note: See also Distance or Length tool.
CAS Specific Syntax
- Length[Function, <Number t1>, <Number t2>]
- Calculates the length of a function graph from point x=t1 to point x=t2.
- Length[Function, <Variable a>, <Number t1>, <Number t2>]
- Calculates the length of a function graph from point a=t1 to point a=t2.
- {{Example|1=
Length[x, 0, 1]
gives you "sqrt(2)".>>
