The Definite Integral Part I: Approximating Areas with rectangles

preview_player
Показать описание
Description: We begin defining integration via a natural problem: what is the area underneath some "nice" curve? We approximate these areas with sums of little rectangles, and think about taking some sort of limit.

Learning Objective
1) Approximate the area under a curve with a left- or right-endpoint approximation

Now it's your turn:
1) Summarize the big idea of this video in your own words
2) Write down anything you are unsure about to think about later
3) What questions for the future do you have? Where are we going with this content?
4) Can you come up with your own sample test problem on this material? Solve it!

Learning mathematics is best done by actually DOING mathematics. A video like this can only ever be a starting point. I might show you the basic ideas, definitions, formulas, and examples, but to truly master calculus means that you have to spend time - a lot of time! - sitting down and trying problems yourself, asking questions, and thinking about mathematics. So before you go on to the next video, pause and go THINK.

This video is part of a Calculus course taught by Dr. Trefor Bazett at the University of Cincinnati.

Dear Trefor - Thank you. Your videos are great. What book would you recommend for Calculus I, II and III for a rapid self study (say inside 1 month)? Thank you again.
