How to Use Riemann Sums for Functions and Graphs

1. How to Use Riemann Sums for Functions and Graphs

Find out how Riemann sums can be used to calculate multiple areas efficiently. In this lesson, you'll learn how this can come in handy for irregular areas and how you can put it to use.

How to Identify and Draw Left, Right and Middle Riemann Sums

2. How to Identify and Draw Left, Right and Middle Riemann Sums

To overestimate or underestimate? In this lesson, you will draw Riemann rectangles so the right side, left side or middle of the rectangle hits the curve.

What is the Trapezoid Rule?

3. What is the Trapezoid Rule?

In this lesson, you'll move beyond simple rectangles to estimate the area under a curve. Get more sophisticated with your approximations and use trapezoids instead of those pesky rectangles.

How to Find the Limits of Riemann Sums

4. How to Find the Limits of Riemann Sums

What would happen if you could draw an infinite number of infinitesimally thin rectangles? You'd get the exact area under a curve! Define the Holy Grail of calculus, the integral, in this lesson.

Definite Integrals: Definition

5. Definite Integrals: Definition

Explore how driving backwards takes you where you've already been as we define definite integrals. This lesson will also teach you the relationship between definite integrals and Riemann sums. Then, discover how an integral changes when it is above and below the x-axis.

How to Use Riemann Sums to Calculate Integrals

6. How to Use Riemann Sums to Calculate Integrals

As a new property owner, you might relish mowing your lawn. Up and down your property you mow and measure out small sections to find the area of your property. In this lesson, you will discover what a Riemann sum approach is and how to calculate an estimated area using multiple slices.

Linear Properties of Definite Integrals

7. Linear Properties of Definite Integrals

If you're having integration problems, this lesson will relate integrals to everyday driving examples. We'll review a few linear properties of definite integrals while practicing with some problems.

Average Value Theorem

8. Average Value Theorem

If you know you've gone 120 miles in 2 hours, you're averaging 60 mph. But what if you know your velocity at every point in time and not how far you've gone? In this lesson, learn how to calculate average values using integrals.

The Fundamental Theorem of Calculus

9. The Fundamental Theorem of Calculus

The fundamental theorem of calculus is one of the most important equations in math. In this lesson we start to explore what the ubiquitous FTOC means as we careen down the road at 30 mph.

Indefinite Integrals as Anti Derivatives

10. Indefinite Integrals as Anti Derivatives

What does an anti-derivative have to do with a derivative? Is a definite integral a self-confident version of an indefinite integral? Learn how to define these in this lesson.

How to Find the Arc Length of a Function

11. How to Find the Arc Length of a Function

You don't always walk in a straight line. Sometimes, you want to know the distance between two points when the path is curved. In this lesson, you'll learn about finding the length of a curve.

Riemann Sums: Formula & Concept

12. Riemann Sums: Formula & Concept

When we want to find the area of the irregular space between the x-axis and a continuous graph, we can't just draw a rectangle in there and take the area; it doesn't fit. If we draw lots of little rectangles, though, it comes closer. If we keep using more and more rectangles that are smaller and smaller, we'll keep getting closer and closer to the true area.

U Substitution: Examples & Concept

13. U Substitution: Examples & Concept

In this lesson, you will learn how to use the substitution technique for integration and also learn to recognize the types of problems with which you can use this method.

Double Integrals: Applications & Examples

14. Double Integrals: Applications & Examples

Double integrals extend the possibilities of one-dimensional integration. In this lesson, we will focus on the application of the double integral for finding enclosed area, volume under a surface, mass specified with a surface density, first and second moments, and the center of mass.

Double Integration: Method, Formulas & Examples

15. Double Integration: Method, Formulas & Examples

In this lesson, we explore the method of double integration, which is useful in finding certain areas, volumes, and masses of objects. Note: knowledge of (single) integrals is a must before tackling double integrals!

Improper Integral: Definition & Examples

16. Improper Integral: Definition & Examples

When integrating a function, infinity might appear in the limits of integration. The function itself could also go to infinity. These types of integrals are called improper integrals, which we will explore in this lesson.
