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.

Mathematics for Machine Learning: Linear Algebra, Module 2 Vectors are objects that move around space To get certificate subscribe at: https://www.coursera.org/learn/linear-algebra-machine-learning/home/welcome ============================ Mathematics for Machine Learning: Linear Algebra: https://www.youtube.com/playlist?list=PL2jykFOD1AWazz20_QRfESiJ2rthDF9-Z ============================ Youtube channel: https://www.youtube.com/user/intrigano ============================ https://scsa.ge/en/online-courses/ https://www.facebook.com/cyberassociation/ About this course: In this course on Linear Algebra we look at what linear algebra is and how it relates to vectors and matrices. Then we look through what vectors and matrices are and how to work with them, including the knotty problem of eigenvalues and eigenvectors, and how to use these to solve problems. Finally we look at how to use these to do fun things with datasets - like how to rotate images of faces and how to extract eigenvectors to look at how the Pagerank algorithm works. Since we're aiming at data-driven applications, we'll be implementing some of these ideas in code, not just on pencil and paper. Towards the end of the course, you'll write code blocks and encounter Jupyter notebooks in Python, but don't worry, these will be quite short, focussed on the concepts, and will guide you through if you’ve not coded before. At the end of this course you will have an intuitive understanding of vectors and matrices that will help you bridge the gap into linear algebra problems, and how to apply these concepts to machine learning. Who is this class for: This course is for people who want to refresh their maths skills in linear algebra, particularly for the purposes of doing data science and machine learning, or learning about data science and machine learning. We look at vectors, matrices and how to apply these to solve linear systems of equations, and how to apply these to computational problems. ________________________________________ Created by: Imperial College London Module 2 Vectors are objects that move around space In this module, we look at operations we can do with vectors - finding the modulus (size), angle between vectors (dot or inner product) and projections of one vector onto another. We can then examine how the entries describing a vector will depend on what vectors we use to define the axes - the basis. That will then let us determine whether a proposed set of basis vectors are what's called 'linearly independent.' This will complete our examination of vectors, allowing us to move on to matrices in module 3 and then start to solve linear algebra problems. Less Learning Objectives • Calculate basic operations (dot product, modulus, negation) on vectors • Calculate a change of basis • Recall linear independence • Identify a linearly independent basis and relate this to the dimensionality of the space

Calculus is a conceptual framework which provides systematic techniques for solving problems. These problems are appropriately applicable to analytic geometry and algebra. Therefore....precalculus gives you the background for the mathematical concepts, problems, issues and techniques that appear in calculus, including trigonometry, functions, complex numbers, vectors, matrices, and others. There you have it ladies and gentlemen....an introduction to precalculus!

Cross products | Essence of linear algebra, Chapter 10

This covers the main geometric intuition behind the 2d and 3d cross products. *Note, in all the computations here, I list the coordinates of the vectors as columns of a matrix, but many textbooks put them in the rows of a matrix instead. It makes no difference for the result, since the determinant is unchanged after a transpose, but given how I've framed most of this series I think it is more intuitive to go with a column-centric approach.

Ti-84 Cross Product Program & Dot Product for Vectors (Triple Scalar Product)
 
04:47
Vector Cross Products are a big thing in Calculus 3, but they can be tedious to calculate due to all the repetitive arithmetic. So I’ve made a program to calculate a cross product for you or use to check an answer. You can easily expand it to use for the Triple Scalar Product of 3 vectors. Download the program http://www.mediafire.com/download/vrj42rkepyqb61c/A2CROSS.8xp ➤Dot products are simple: -2nd STAT -Left arrow to "MATH" -option 5 is sum( -type your 2 vectors in curly braces separated by commas -sum( {1,2,3}{3,4,5} -Press Enter & you’ve got the answer ➤Cross Products program: Input "{A,B,C}=",L3 Input "{D,E,F}=",L4 Disp "AXB=",{L3(2)L4(3)-L3(3)L4(2),L3(3)L4(1)-L3(1)L4(3),L3(1)L4(2)-L3(2)L4(1)} You could paste these 3 lines into the cemetech editor and create your own program https://www.cemetech.net/sc/ ➤When running the program you must enter the vectors in curly braces (the last one is optional) -So when it prompts "{A,B,C}=" you enter "{1,2,3" The program’s answer is a list NOT an actual vector (e.g. {2 4 5} (Notice no commas) If you need to use it as a vector, copy it manually ➤Scalar Triple Product: -is defined by a•(bXc) or b•(aXc) -so do a cross product first -then dot product that answer with the third vector Cross Product Definition http://www.mathportal.org/linear-algebra/vectors/cross-product.php Slightly Modified source https://answers.yahoo.com/question/index?qid=20110207191241AAOr0XA
