LeftSum Command
From GeoGebra Manual
- LeftSum( <Function>, <Start x-Value>, <End x-Value>, <Number of Rectangles> )
- Calculates the left sum of the function in the interval using n rectangles.
- Example:
LeftSum(x^2 + 1, 0, 2, 4)
yields a = 3.75
- Notes:
- This command draws the rectangles of the left sum as well.
- This command is designed as a visual aid so won't give accurate answers if the number of rectangles is too large.
- See also the commands: RectangleSum, TrapezoidalSum, LowerSum and UpperSum.
