Introduction to integral calculus

mathswithmuza on Instagram: "The rectangle rule and the trapezoid rule are numerical methods for estimating the area under a curve, which is a fundamental problem in calculus. The rectangle rule approximates the area by dividing the interval into equal parts and using the height of the function at specific points (usually left, right, or midpoint) to form rectangles. It’s simple but can be inaccurate if the function changes rapidly. The trapezoid rule improves on this by treating each subinterva
