Is called the Fourier series associated to the function f(x) Remark Notice that we are not saying f(x) is equal to its Fourier Series Later we will discuss conditions under which that is actually true Example Find the Fourier coefficients and the Fourier series of the squarewave function f defined by f(x) = ˆ 0 if −π ≤ x <. X 2, then f ⁡ (x) is nondecreasing on I If the ≤ sign is replaced by <, then f ⁡ (x) is increasing (also called strictly increasing) on I Similarly for nonincreasing and decreasing (strictly decreasing) functions.

Intuitively, a function is a process that associates each element of a set X, to a single element of a set Y Formally, a function ffrom a set Xto a set Yis defined by a set Gof ordered pairs (x, y)with x∈ X, y∈ Y, such that every element of Xis the first component of exactly one ordered pair in G.

C n, which must converge since x= 1 is within the interval of convergence When we substitute x= 0 we get P c n2n, which we have been told diverges The series converges at x= 1 and at x= 3 and diverges at x= 1 and x= 10 6Say that f(x) = P 1 n=0 ( 1) n x2n1 (2 1)!. Where x is a variable of indeterminate It can be interpreted as an infinite polynomial The cn’s are the coefficients of the series The sum of the series is a function f(x) = X∞ n=0 c0x n For instance the following series converges to the function shown for −1 <.
