It gives an overestimate of the area under the curve.
The upper bound is 252525 when xxx is at its maximum value.
Area = ∫05x2dx=1253≈41.67\int_0^5 x^2 dx = \frac{125}{3} \approx 41.67∫05x2dx=3125≈41.67.
It uses rectangles that touch the curve's left-hand side.
Use the smallest value of xxx, then square it.
LB is min, UB is max value of the integrand over the interval.
It provides an estimate of the area under a curve.
The tops of trapeziums lie above the curve.
Using h=1h = 1h=1, result: 852\frac{85}{2}285.
Using more or thinner strips enhances accuracy.
