Matrix Transformations and Linear Transformations | Linear Algebra

We introduce matrix transformations and their equivalence with linear transformations from R^n to R^m. We'll give examples of linear transformations, see some important properties of matrix transformations including the homogeneity property and additivity properties. We'll also see functions that aren't matrix transformations and we will prove they aren't matrix transformations. We finish by going over how to find the standard matrix for a linear transformation. #linearalgebra Linear Algebra course: https://www.youtube.com/playlist?list=PLztBpqftvzxWT5z53AxSqkSaWDhAeToDG Linear Algebra exercises: https://www.youtube.com/playlist?list=PLztBpqftvzxVmiiFW7KtPwBpnHNkTVeJc Join Wrath of Math to get exclusive videos, music, and more: https://www.youtube.com/channel/UCyEKvaxi8mt9FMc62MHcliw/join 0:00 Intro 0:20 What is a Matrix Transformation 4:45 Example of Matrix Transformation 6:30 Properties of a Matrix Transformation 7:58 Transformations of Linear Combinations 8:46 Non-Examples of Matrix Transformations 10:58 Two Key Questions 11:23 Homogeneity and Additivity 11:49 Linear Transform 12:30 Finding Standard Matrix for a Linear Transformation 13:35 Standard Matrix Example 15:15 Conclusion ◉Textbooks I Like◉ Graph Theory: https://amzn.to/3JHQtZj Real Analysis: https://amzn.to/3CMdgjI Abstract Algebra: https://amzn.to/3IjoZaO Linear Algebra: https://amzn.to/43xAWEz Calculus: https://amzn.to/3PieD1M Proofs and Set Theory: https://amzn.to/367VBXP (available for free online) Statistics: https://amzn.to/3tsaEER Discrete Math: https://amzn.to/3qfhoUn Number Theory: https://amzn.to/3JqpOQd ★DONATE★ ◆ Support Wrath of Math on Patreon for early access to new videos and other exclusive benefits: https://www.patreon.com/join/wrathofmathlessons ◆ Donate on PayPal: https://www.paypal.me/wrathofmath Thanks to Loke Tan, Raül Beienheimer, Matt Venia, Micheline, Doug Walker, Odd Hultberg, Marc, Shlome Ashkenazi, Barbora Sharrock, Mohamad Nossier, Rolf Waefler, Shadow Master, and James Mead for their generous support on Patreon!
