- Min( <List> )
- Returns the minimum of the numbers within the list.
- Example:
Min({-2, 12, -23, 17, 15})
yields -23.
- Note: If the input consists of non-numeric objects, then this command considers the numbers associated with those objects. If you have a list of segments for example, the command Min( <List> ) will yield the minimum segment length.
- Min( <Interval> )
- Returns the lower bound of the interval.
- Example:
Min(2 < x < 3)
yields 2 .
- Note: Open and closed intervals are not distinguished.
- Min( <Number>, <Number> )
- Returns the minimum of the two given numbers.
- Example:
Min(12, 15)
yields 12.
- Min( <Function>, <Start x-Value>, <End x-Value> )
- Calculates (numerically) the local minimum point for function in the given interval. Function should be continuous and have only one local minimum point in the interval (and no local maximum).
- Note: For polynomials you should use the Extremum Command.
- Example:
Min(exp(x) x^3,-4,-2)
creates the point (-3, -1.34425) .
- Min( <List of Data>, <List of Frequencies> )
- Returns the minimum of the list of data with corresponding frequencies.
- Example:
Min({1, 2, 3, 4, 5}, {0, 3, 4, 2, 3})
yields 2, the lowest number of the first list whose frequency is greater than 0.
Note:
- If you want the minimum of two functions
f(x)
andg(x)
then you can define(f(x) + g(x) - abs(f(x) - g(x)))/2
- See also Max Command, Extremum Command and Function Inspector Tool.
CAS Syntax
- Min( <Function>, <Start x-Value>, <End x-Value> )
- Unlike in the Algebra View, this syntax will give the minimum over the interval, including endpoints
- Example:
Min(x^2,-1,2)
yields the point (0,0)Min(-x^2,-1,2)
yields the point (2,-4)
