Latest revision as of 15:57, 17 November 2017

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.
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: LowerSum, LeftSum, RectangleSum and UpperSum.
