Finding and Classifying Geometric Sequences

3. Finding and Classifying Geometric Sequences

Want your YouTube video to get a lot of hits? Besides including a cute baby or an adorable cat, getting your video to have a big common ratio is the key. Learn what I'm talking about here!

Summation Notation and Mathematical Series

4. Summation Notation and Mathematical Series

The capital Greek letter sigma might be most recognizable as a common symbol in a fraternity or sorority, but it's used for some pretty cool math tricks too. In this lesson, learn how to use sigma for things like determining how many seats are in Michigan Stadium.

How to Calculate an Arithmetic Series

5. How to Calculate an Arithmetic Series

In this lesson, you'll learn how to sum up any arithmetic sequence without having to add up each and every term. You'll never guess the circumstances that led to the discovery of this marvelous formula.

How to Calculate a Geometric Series

6. How to Calculate a Geometric Series

If you're not satisfied with knowing how many views your YouTube video will get any one day and need to know how many total views you're getting, geometric series are for you! Learn more in this lesson.

Arithmetic and Geometric Series: Practice Problems

7. Arithmetic and Geometric Series: Practice Problems

There are many different types of problems concerning series and sequences - including some that are pretty abstract. From bouncing balls to adding up odd numbers, test your skills here with additional arithmetic and geometric series practice!

Arithmetic Series: Formula & Equation

8. Arithmetic Series: Formula & Equation

After this lesson, you will be able to identify summation notation and interpret each of its parts when used for an arithmetic series. You will also be able to find the sum of an arithmetic series.

Harmonic Series in Math: Definition & Formula

9. Harmonic Series in Math: Definition & Formula

The harmonic series provides one of the most important counter-intuitive examples in the study of mathematics. In the harmonic series, the numbers or terms get closer and closer to zero, while the series itself diverges.

Infinite Series: Applications, Formula & Examples

10. Infinite Series: Applications, Formula & Examples

An infinite series, represented by the capital letter sigma, is the operation of adding an infinite number of terms together. This summation will either converge to a limit or diverge to infinity.

Maclaurin Series for ln(1+x): How-to & Steps

11. Maclaurin Series for ln(1+x): How-to & Steps

In this lesson, we show how to find the Maclaurin series for a particular function: ln(1 + x). In addition to the steps for finding this series, you will also learn how to determine its region of convergence.
