5.2 Interchange of Limits and Integrals/ Derivatives 9) Calculate n cos lim -dr, 2n sin2 J2 justifying your calculation 10) Let 2nx fn(x) 1 +n2z2E0, 1], n > 1. Show that (fn) converges pointwise, but not uniformly, on [0,1] (b) Show that nevertheless, fa(a)d lim fa(a)dx. lim (This shows that the hypotheses of Theorem 5.8 are sufficient, but not nec- essary, for interchanging limits and integrals.)
