1 Magic Squares - UC Santa Barbara

1 Magic Squares De nition. A magic square is a n n grid lled with the integers f0;1;:::n2 1g, such that each number is used exactly once in our entire grid, and the sum of all of the entries along any row, column, the main diagonal2 or the main antidiagonal all come out to the same constant value. Here’s an example for order 3:

Laplace Transform: Examples Def: Given a function f(t) de ned for t>0. Its Laplace transform is the function, denoted F(s) = Lffg(s), de ned by: F(s) = Lffg(s) = Z 1 0 e stf(t)dt: (Issue: The Laplace transform is an improper integral. So, does it always exist? i.e.: Is the function F(s) always nite?
