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:

Factoring Cubic Polynomials - UC Santa Barbara

Factoring Cubic Polynomials March 3, 2016 A cubic polynomial is of the form p(x) = a 3x3 + a 2x2 + a 1x+ a 0: The Fundamental Theorem of Algebra guarantees that if a 0;a 1;a 2;a 3 are all real numbers, then we can factor my polynomial into the form

R x p 1 x4dx Solution: Z x p 1 x4dx= x 1 (x2)2dx Let u= x2, then du= 2xdx: Z x p 1 (x2)2dx= 1 2 Z 1 u2du Now let u= sin , then du= cos d : 1 2 Z p 1 u2du= 1 2 Z 1 sin2 cos d = 1 2 Z cos2 d = 1 4 Z (1+cos2 )d = 1 4 + 1 2 sin2 +C= 1 4 ( +sin cos )+C Plug back in u. Since u= sin , the opposite side will be u, the hypotenuse will be 1, and the
