Differential Equations - Linear Independence - Definition of Basis
Video showing some extended results surrounding linear independence of sets of vectors. It is shown that, in a set of n-component vectors, you can have at most n of them being linearly independent. From that, a basis is defined and it is shown that, in less technical terms, a set of n-linearly independent n-component vectors is automatically a spanning set for all n-component vectors. Implications are made for how this will connect to differential equations later on.

Differential Equations - Second Order Equations - Theory of Linear Independence
Переглядів 921 день тому
Video showing the definition and theory of linear independence of solutions to a second order linear differential equations. The definition of linear independence is shown along with the uniqueness theorem for these types of equations. Then, the two of these are combined to prove that two solutions are linearly independent if and only if the Wronskian of the solutions is non-zero.
