[UT#16] Formules de changements de bases - D'où ?!

👁️ A new version of this show is now available! 🎥[UT#16] Change of Base Formulas - Where?! (Introduction) -    • [UT#16] Formules de changement de bases – ...   In this video, I perform a change of base to obtain a nice matrix representing a cyclic endomorphism. I explain how a change of base can be performed manually without knowing the so-called "change of base" formulas. Then, I show how these formulas can be made to appear in the context of this example, in the hopes that you can understand what these formulas correspond to in a concrete example and where they come from. Corratum: 2:02 - The first coefficient of the column vector is a+2b+2c and not a+2b+c. 3:00 - The coefficient in the third row and second column is -2 and not -1. 5:47 - This is to be read as α + β - γ, not α + β - α. ⏱️ Some time markers: 00:00 Introduction 00:33 Exercise statement 01:11 Appendix 1 - What is endomorphism? 02:39 Appendix 2 - Why is B' a base? 03:20 Change of base - Manual method 07:00 Explanation of the first change of base formula 10:00 Explanation of the second change of base formula 11:36 Show summary 13:02 Conclusion 🌞 Enjoy! 📚 Discover my training courses! - https://www.oljen.fr/formations 🎁 Dedalus Fecit (Free excerpts) - https://formations.oljen.fr/courses/d... 🎁 Lux in Tenebris (Free excerpts) - https://formations.oljen.fr/courses/l... 🤖 Join my Discord server! -   / discord   🌐 Explore my website! - https://www.oljen.fr/ 📧 Contact - https://www.oljen.fr/contact 🔸Do you like the content I produce? 🔸Would you like me to make more videos? 🔸Would you like to thank me for what this channel has brought you? 👨‍🏫 Support me by joining the channel! -    / @oljenmaths   🤝🏻 You can also make a voluntary donation here! - https://www.paypal.com/donate/?hosted... 📗 The Little Khôlle Manual - https://www.amazon.fr/gp/product/1707... 📘 The Principles of a Successful Year – https://www.amazon.fr/gp/product/1089...
