7.3 The Dot Product Explained

0:00 Introduction 0:33 Definition of the dot product explained 2:14 Dot product example calculation 3:28 How to calculate the angle between two nonzero vectors 8:48 How to test whether two vectors are perpendicular 11:45 The properties of the dot product 12:47 Derivation of the equation for the angle between two nonzero vectors 22:14 Summary 22:43 End screen In this video I explain the dot product (also referred to as the inner product, or scalar product), and I discuss the topics listed in the timestamps above. The dot product of two vectors results in a scalar value. The dot product is a key part of the calculation of the angle between two nonzero vectors. We can also use the dot product to test whether two vectors are perpendicular. For an introduction to vectors, please watch the following video:    • 7.1 Introduction to Vectors
