Riemann Sums and Their Applications

The video tutorial explains the concept of Riemann sums, focusing on both left-side and right-side approaches. It demonstrates how to approximate the area under a curve using these methods, with examples and mathematical calculations. The tutorial also discusses the concepts of lower and upper sums, providing a comprehensive understanding of how these methods are used in calculus to estimate areas.

What is the purpose of using Riemann sums in calculus?

• To calculate the slope of a tangent line

• To approximate the area under a curve

• To determine the maximum value of a function

• To find the exact area under a curve
