Over- and under-estimation of Riemann sums - Khan …
WebIf our function is concave up, the trapezoids we get from the trapezoid rule cover too much area, so we get an overestimate. If our function is concave down, the trapezoids don't cover enough area, so we get an underestimate. If our function has no concavity (is a straight line), the trapezoid sum is just right.
