This command differs among variants of English:
|
- TrapezoidalSum( <Function>, <Start x-Value>, <End x-Value>, <Number of Trapezoids> )
- Calculates the trapezoidal sum of the function in the interval [Start x-Value, End x-Value] using n trapezoids.
- Example:
TrapezoidalSum[x^2, -2, 3, 5]yields 12.5.
Notes:
- This command draws the trapezoids of the trapezoidal sum as well.
- See also the commands: LowerSum, LeftSum, RectangleSum and UpperSum.
