Problems
In Problems 1-10 find power series for f'(x) and for ∫0xf(t) dt. In Problems 11-34 find a power series for the given function and determine its radius of convergence. 35 Check the formulas d(sinh x)/dx = cosh x, d(cosh x)/dx = sinh x by differentiating the power series. 36 Prove that if the power serieshas finite radius of convergence r, then the power series has radius of convergence r/b (b > 0). 37 Prove that if has finite radius of convergence r, then has radius of convergence √r. 38 Prove that if have radii of convergence r and s respectively and r ≤ s, then f(x) + g(x) has a radius of convergence of at least r. 39 Show that if has radius of convergence r, then for any positive integer p, has radius of convergence r. 40 Evaluate , using the derivative of the power series 41 Evaluate , using the first and second derivatives of
