RectangleSum( <Function>, <Start x-Value>, <End x-Value>, <Number of Rectangles>, <Position for rectangle start> )
Calculates between the Start x-Value and the End x-Value the sum of rectangles with left height starting at a fraction d (0 ≤ d ≤ 1) of each interval, using n rectangles.
When d = 0 it is equivalent to the LeftSum command, and when d = 1 it computes the right sum of the given function.
Note:
  • 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: UpperSum, LowerSum, LeftSum , TrapezoidalSum.
