# Ch 8: WEST Math: Vector Operations

### About This Chapter

## WEST Math - Vector Operations - Chapter Summary

The video lessons in this chapter will help prepare you for the WEST math examination by strengthening your ability to solve problems through the use of vector operations. Watch the lessons to review what you know about the geometric approach to subtracting vectors and the process of calculating a resultant vector. This chapter will remind you how to:

- Define a vector and explain its different types
- Complete vector addition and subtraction problems
- Explain the purpose of a resultant vector
- Perform scalar multiplication of vectors

Study these short, educational video lessons in preparation for passing the WEST math examination. The video lessons are taught by experienced educators, and they include corresponding written transcripts. Work at your own pace, submit your questions to qualified instructors and use the video tags to re-watch parts of the lessons. After reviewing the videos, take the convenient self-assessment quizzes and practice chapter examination to test your knowledge.

### WEST Math - Vector Operations Objectives

You'll answer questions pertaining to vector operations on the Statistics, Probability and Discrete Mathematics portion of the WEST Math examination, which is the fifth and final part of the test. That section will account for 19% of your examination score.

To qualify for a mathematics endorsement to your Washington teaching certificate, you'll demonstrate your ability to analyze sequences and series, and to apply set theories in order to solve problems. The WEST math examination is computer-based. It includes 150 multiple-choice questions that must be answered in four hours and 15 minutes.

### 1. What Is a Vector? - Definition & Types

After watching this lesson, you will be able to explain what vectors are in physics, give some examples of vectors and have a basic idea of how they can be manipulated mathematically. A short quiz will follow.

### 2. Vector Addition (Geometric Approach): Explanation & Examples

After watching this video, you will be able to explain why we might need to add two vectors and, given magnitudes and directions, add two vectors using geometric methods. A short quiz will follow.

### 3. Vector Subtraction (Geometric): Formula & Examples

After watching this lesson, you will be able to subtract vectors geometrically and give examples of how that process might be used in physics. A short quiz will follow.

### 4. Resultants of Vectors: Definition & Calculation

After watching this video, you will be able to explain what a resultant of a vector is and use mathematics to calculate the resultant of two vectors. A short quiz will follow.

### 5. Scalar Multiplication of Vectors: Definition & Calculations

After watching this video, you will be able to explain what scalar multiplication is and complete basic calculations involving the scalar multiplication of vectors. A short quiz will follow.
