QUESTION about Macroeconomics, derivation of the fisher equation.

4. Complete the steps in the derivation of the Fisher equation discussed on slide 17 of lecture 3 by showing that if we (a) Begin with 1 +i 1+ TC 1 +r. (b) Replace 1+ TC with the Taylor-series expansion 1 + 76 =1-7 + (7)2 - (75)3 + (45)1 -. . . in the expression in part 4(a) above. (c) Assume that we can ignore any terms involving in" or (7")" for n > 2 because T is small. that we are left with the Fisher equation r - 1 -7
