- nivter 3y agoThis was a joyful epiphany for me when I encountered continuous linear systems for the first time. Another corollary of this is when the kernel is δ(x-y), the resulting integral has the value f(x). I like to see it as a continuous version of expressing a vector as a sum of its components.
