Learn how to use the trapezoidal rule with 4 sub intervals

The video tutorial covers the concept of trapezoids, focusing on calculating their area using the formula: area = 1/2 * (base1 + base2) * height. The instructor explains how to reframe trapezoids and introduces the concept of delta X. A detailed step-by-step calculation of trapezoid areas is provided, followed by a simplification of the formula. The tutorial emphasizes understanding the pattern in the formula and the importance of uniform delta X for simplification.
