Scalar (dot) Product with Worked Examples

In this video, we will be learning about the dot product of vectors. We'll start by reviewing the basic of vectors, the concept of scalar multiplication and the scalar product of vectors also known as dot product. We will then cover the method of calculating the dot product of two vectors. We will also discuss the use of the dot product to find the angle between two vectors. We'll work through several example problems to help solidify your understanding of the material. By the end of this video, you will have a solid understanding of dot product and be able to use it to solve problems confidently. This video is designed for the NSW HSC Extension 1 Mathematics Course.
