Q

Riemann Sums

A

The Left Hand Rule says to evaluate the function at the left-hand endpoint of the subinterval and make the rectangle that height. In , the rectangle labelled “LHR” is drawn on the interval [2,3] with a height determined by the Left Hand Rule, namely f(2)=4.

The Right Hand Rule says the opposite: In
, the rectangle labelled “RHR” is drawn on the interval [0,1] with a height determined by the Right Hand Rule, namely f(1)=3.

Then take the average of both

Q

Midpoint rule

A

The Midpoint Rule says that on each subinterval, evaluate the function at the midpoint and make the rectangle that height. In , the rectangle labelled “MPR” is drawn on the interval [1,2] with a height determined by the Midpoint Rule, namely f(1.5)=3.75.
