Riemann rectangles are a visual and conceptual way to approximate the area under a curve by dividing the interval on the x-axis into smaller subintervals and drawing rectangles over each one. The height of each rectangle is determined by the value of the function at a specific point within that subinterval—this could be the left endpoint, right endpoint, or midpoint. As the number of rectangles increases (meaning the width of each one decreases), the total area of all the rectangles gets closer

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
