Problem 2 Let fn(x) = Sm ) be a sequence of functions. Show that the series sin (nx) E fn (x) = E 6) = Ë n2 n=1 n=1 converges for all values of x but the series of derivatives E1 f(x) diverges when.x= 2kt where k is an integer. This problem gives us an example where for infinite sums, the derivative of n=1 Jn a sum is not the sum of the derivatives.
