School’s in session. Let’s talk about math. Go back to your calculus class senior year in high school. You take the derivative of y with respect to x. You are finding the sensitivity to the change in ...

Let's try a simple linear function: f ( x) = x + c, where c is a constant. So, f ( x) = x + c is a solution for any a and any ...

Let A → Ar be the map that takes a positive definite matrix to its rth power, and let DAr be the Fréchet derivative of this map. It is known that ∥DAr∥ = ∥rAr−1∥ if r ≤ 1 or if r ≥ 2, and also that ...
