Dot products and duality | Essence of linear algebra, chapter 9
 
14:12
Dot products are a nice geometric tool for understanding projection. But now that we know about linear transformations, we can get a deeper feel for what's going on with the dot product, and the connection between its numerical computation and its geometric interpretation.

Lines and Planes: Vector and Dot product forms: Linear Algebra
 
23:27
In this video, we work through exam style questions on vectors, lines and plains. 1. We find the direction cosines of line that is perpendicular to 2 other lines by finding its direction vector through the cross product. 2. We find the equation of a plane which contains a known line by using the plane's dot product form. 3. We find the equation of a plane which is at a known acute angle to a defined line. 4. We find the vector product form of a line where 2 planes intersect. This is a worked solution of question 8 from the AQA MFP4 June 2017 Paper. Thanks for watching.

Dot product of two vectors : Motion in a Straight Line
 
05:45
Dot product of two vectors is a part of vectors and it is discussed in a topic called motion in a straight line. If we multiply two vectors and if we get a scalar then the product of two vectors is called scalar product and dot product. Venkats Academy is a Complete Physics Resource for preparing IIT-JEE,NEET,CBSE,ICSE and IGCSE. All Physics topics are divided into multiple sub topics and are explained in detail using concept videos and synopsis.Lots of problems in each topic are solved to understand the concepts clearly.
