What is a null space? Please feel free to find it out.
Thank you for your kind support.
Currently exploring the essence of the direct sum concept in applications like solving linear equations and calculating matrices.
Learning and exploration strategy: For each fundamental concept introduced by Sheldon Axler, I will explore its essence and application to the linear algebra calculations.
We need to ensure a solid grasp of concepts, notations, and theorems in order to prevent the calculations of linear algebra from becoming totally abstract.
