Trapezoidal Rule for Integration (Definition, Formula

Key idea: By using trapezoids (aka the trapezoid rule) we can get more accurate approximations than by using rectangles (aka Riemann sums). An example of the trapezoid rule Let's check it

Trapezoidal rule to estimate area under the curve

Trapezoidal Rule Formula Let f (x) be a continuous function on the interval [a, b]. Now divide the intervals [a, b] into n equal subintervals with each of width, Δx =
