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:

Math 2260 Exam #1 Practice Problem Solutions 1.What is the area bounded by the curves y= x2 1 and y= 2x+ 7? Answer: As we can see in the gure, the line y= 2x+ 7 lies above the parabola y= x2 1 in the region we care about. Also, the points of intersection occur when 2x+ 7 = x2 1 or, equivalently, when 0 = x2 2x 8 = (x 4)(x+ 2);
