Find Rank of a Matrix in Seconds! | Linear Algebra Exercises

To find the rank of a matrix by inspection, we must try to identify how many linearly independent rows or columns it has. If the matrix or its transpose is in row echelon form, this can be done by counting the number of nonzero rows or columns. Otherwise, we need to consider linear combinations of the rows or columns and how one might be created from the others. We do several practice problems in this video, in each case finding the matrix rank with little more than a pinch of thought. #linearalgebra How to Find the Rank of a Matrix:    • How to Find the Rank of a Matrix (wit...   Linear Algebra course:    • Linear Algebra   Linear Algebra exercises:    • Linear Algebra Exercises   ◉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:   / wrathofmathlessons   ◆ Donate on PayPal: https://www.paypal.me/wrathofmath Thanks to Loke Tan, Matt Venia, Micheline, Doug Walker, Odd Hultberg, Marc, Roslyn Goddard, Shlome Ashkenazi, Barbora Sharrock, Mohamad Nossier, Rolf Waefler, Shadow Master, and James Mead for their generous support on Patreon!
