In calculus, the derivative of any linear combination of functions equals the same linear combination of the derivatives of the functions; this property is known as linearity of differentiation, the rule of linearity, or the superposition rule for differentiation. It is a fundamental property of the derivative that encapsulates in a single rule two simpler rules of differentiation, the sum rule (the derivative of the sum of two functions is the sum of the derivatives) and the constant factor rule (the derivative of a constant multiple of a function is the same constant multiple of the derivative). Thus it can be said that differentiation is linear, or the differential operator is a linear operator. (Wikipedia).

Differential Equations: Linearity
Linearity is crucial throughout mathematics. In this video, I demonstrate the linearity of linear differential equations and explain why it can be useful. This video is the first precursor to our discussion of homogeneous differential equations.

Differential Equations: Linear Independence
Linear independence is a core idea from Linear Algebra. Surprisingly, it's also important in differential equations. This video is the second precursor to our discussion of homogeneous differential equations.

Definition of Rank and showing Rank(A) = Dim Col(A) In this video, I define the notion of rank of a matrix and I show that it is the same as the dimension of the column space of that matrix. This is another illustration of the beautiful interplay between linear transformations and matrice

In this video, I'm do something really cool! I calculate the derivative of a function without using calculus, but using linear algebra instead. Well, almost without calculus, since I still need to know the derivatives of 1, x, x^2. This little exercise is a beautiful illustration of the in

Are derivatives linearly independent ?
In this video, I show that the differentiation transformations D, D^2, and D^3 are linearly independent (where Df = f' etc.) This result can be easily generalized to n transformations. It's a great exercise in showing that abstract linear transformations are linearly independent, enjoy! C
