Upper Riemann Sum

 

Calling Sequence

Parameters

Description

Examples

Other Riemann Sums

Calling Sequence

RiemannSum(f(x), x = a..b, method = upper, opts)

RiemannSum(f(x), a..b, method = upper, opts)

RiemannSum(Int(f(x), x = a..b), method = upper, opts)

Parameters

f(x)

-

algebraic expression in variable 'x'

x

-

name; specify the independent variable

a, b

-

algebraic expressions; specify the interval

opts

-

equation(s) of the form option=value where option is one of boxoptions, functionoptions, iterations, method, outline, output, partition, pointoptions, refinement, showarea, showfunction, showpoints, subpartition, view, or Student plot options; specify output options

Description

• 

The RiemannSum(f(x), x = a..b, method = upper, opts) command calculates the upper Riemann sum of f(x) from a to b. The first two arguments (function expression and range) can be replaced by a definite integral.

• 

If the independent variable can be uniquely determined from the expression, the parameter x need not be included in the calling sequence.

• 

Given a partition P=a=x0,x1,...,xN=b of the interval a,b, the upper Riemann sum is defined as:

i=1Nfxi* xixi1

  

where the chosen point of each subinterval xi1,xi of the partition is a point xi*  such that fxfxi* for all x in xi1,xi.

• 

By default, the interval is divided into 10 equal-sized subintervals.

• 

For the options opts, see the RiemannSum help page.

• 

This integration method can be applied interactively, through the ApproximateInt Tutor.
