Final Exam (in the time slot on the final exam
schedule). About half of the final exam
will cover material from Chapters 9, 10, and 11; the other half of the final
exam will cover Chapters 7, 9, 10, and 11. 
The following errors in the textbook The
Theory of Interest need to be corrected:
(1) The denominator of the middle expression of formula (1.12) on page 13 needs to be changed from “(1 + t)^{t}^{ }” to “(1 + i)^{i}^{ }”.
(2) The left side of formula (4.31a) on page 134 needs to be changed from “ i + i^{/} ” to “ 1 + i^{/} ”.
(3) The last term in the formula immediately above formula (4.38) on page 138 needs to be changed

from 
n — v k 
to 
n — v^{n} . k 
(4) Immediately above formula (5.11) on page 173, the exponent of the terms in the summation from t=1 to t=n needs to be changed from “n–1” to “n–t”.
(5) In the first complete sentence at the top of page 218, the word “form” needs to be changed to the word “from”.
(6) The answer to Chapter 3 Exercise #38 needs to be changed in the back of the text from 14.5 to 13.37543.
(7) In Chapter 6 Exercise #38, the word “tears” needs to be changed to the word “years”.
(8) In ???????????, the word “matter” needs to be changed to the word “manner”.
