PARTIAL DIFFERENTIAL EQUATIONS

PARTIAL DIFFERENTIAL EQUATIONSMath 124A Fall 2010 Viktor of MathematicsUniversity of California, Santa BarbaraThese lecture notes arose from the course PARTIAL DIFFERENTIAL EQUATIONS Math124A taught by the author in the Department of Mathematics at UCSB in the fallquarters of 2009 and 2010. The selection of topics and the order in which theyare introduced is based on [Str]. Most of the problems appearing in this text arealso borrowed from Strauss. A list of other references that were consulted whileteaching this course appears in the bibliography at the notes are copylefted, and may be freely used for noncommercial educationalpurposes.

1 Magic Squares - UC Santa Barbara

web.math.ucsb.edu

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:

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
