About This Chapter

The Vectors in Linear Algebra chapter of this Linear Algebra Tutoring Solution is a flexible and affordable path to learning about vectors. These simple and fun video lessons are each about five minutes long and they teach the definition of vectors and how to perform operations on vectors as required in a typical linear algebra course.

How it works:

  • Begin your assignment or other linear algebra work.
  • Identify the vector concepts that you're stuck on.
  • Find fun videos on the topics you need to understand.
  • Press play, watch and learn!
  • Complete the quizzes to test your understanding.
  • As needed, submit a question to one of our instructors for personalized support.

Who's it for?

This chapter of our Linear Algebra Tutoring Solution will benefit any student who is trying to learn vectors in linear algebra and earn better grades. This resource can help students including those who:

  • Struggle with understanding scalars and vectors, the dot product of vectors, the basis of a vector space or any other vectors in linear algebra topic
  • Have limited time for studying
  • Want a cost effective way to supplement their math learning
  • Prefer learning math visually
  • Find themselves failing or close to failing their vectors in linear algebra unit

Scalars and Vectors: Definition and Difference

1. Scalars and Vectors: Definition and Difference

In this lesson, we will examine scalars and vectors, learn why it is important to know the difference between the two and why remembering to add a direction to many of your exam answers could be the reason you get it right or wrong.

How to Find a Column Vector

2. How to Find a Column Vector

A column vector is a vertical notation for a vector. In this lesson, we will go through what a column vector is and how to do some mathematical operations with column vectors.

Performing Operations on Vectors in the Plane

3. Performing Operations on Vectors in the Plane

After watching this video lesson, you should be able to add, subtract, and multiply your vectors. Learn how easy it is to perform these operations and what you need to keep in mind when performing these operations.

Difference Between a Row & Column Vector

4. Difference Between a Row & Column Vector

Learn how row and column vectors differ by viewing them through matrix notation. Then explore some unique interactions between row and column vectors by seeing how a couple types of matrix operations work on them.

The Dot Product of Vectors: Definition & Application

5. The Dot Product of Vectors: Definition & Application

After watching this video lesson, you will be able to find the dot product of vectors both algebraically and geometrically. Learn the difference between the two and what you need in order to calculate them.

Vector Spaces: Definition & Example

6. Vector Spaces: Definition & Example

In this lesson, we'll discuss the definition and provide some common examples of vector spaces. We'll go over set theory, the axioms for vector spaces, and examples of axioms using vector spaces of the real numbers over a field of real numbers.

Finding the Basis of a Vector Space

7. Finding the Basis of a Vector Space

In this lesson we'll start by reviewing matrix reduced row echelon form, which is integral to finding a basis of a vector space. Then we'll work through a problem together to see exactly how finding a basis is accomplished.

Orthonormal Bases: Definition & Example

8. Orthonormal Bases: Definition & Example

In this lesson we show how independent vectors in a space can become a basis for the space and how this basis can be turned into an orthonormal basis. Having an orthonormal basis is useful in many applications involving vectors.

The Gram-Schmidt Process for Orthonormalizing Vectors

9. The Gram-Schmidt Process for Orthonormalizing Vectors

Linearly combining things is something we do quite naturally. When the things are vectors, there is a fantastic way to organize the vectors before combining them. In this lesson, we'll show how to orthonormalize vectors using the Gram-Schmidt process.

Linear Combinations & Span: Definition & Equation

10. Linear Combinations & Span: Definition & Equation

This lesson will cover the definitions of linear combinations and spans in terms of vector spaces, using a real world example and then a mathematical example. You will learn the official definitions and how to apply them in mathematics.

Linear Dependence & Independence: Definition & Examples

11. Linear Dependence & Independence: Definition & Examples

Linear dependence and independence are based on whether or not there is more than one solution to a system of equations. In this lesson, we'll look at how you can determine whether or not a system is independent and work through some examples.
