The second set of questions is about the Fibonacci numbers. Recall that the Fibonacci sequence is a sequence of numbers fn defined by the fact that fi = 1, fa = 1, and for n 2 3, fn = fn-1 + fn-2- 1 a) Consider the rational function Find the first four terms of the Taylor Series centered at r = 0 of this function. Notice anything? 1 1b) Show that the Taylor Series centered at r= 0 of f(r) is precisely n-1 where fn is the Fibonacci Sequence. (Hint: Do not attempt this by doing calculus. Instead, set the series equal to f(1) and solve successively for the coefficients of that power series.) 1c) Note that -r-r+1 is a reducible polynomial over the reals with roots r= A. Use this to find a partial fraction decomposition for f(1). 1d) Use the partial fraction decomposition for f(r) to find an alternative power series representation for the function, and conclude that fn
