AISL 5.8 Trapezoidal rule

The video explains the trapezoidal rule, a numerical method used to estimate the area under a curve. It begins by contrasting the trapezoidal approximation with the exact area obtained through integration, emphasizing that while the integral provides an exact value, the trapezoidal rule offers an estimate that can be improved by increasing the number of trapezoids.

Key points include:

• The formula for the area of a trapezoid is given by $A = \frac{1}{2} (x_1 + x_2) h$, where is the height between the trapezoids.
