You can now find a PDF that prints well at the bottom of my original post:

Unless someone shows me how to make a proper annuity symbol angle in LaTeX or points out a serious error this will probably be the last revision. Enjoy!
One more update, cleaned up the appearance (annuity angles should print nicely, though some of them look a little funny on my screen), increased spacing between the lines for a little easier legibility in the formulas, and a couple of other cosmetic changes. The revised version (2.01) is at the bottom of my initial post.

Here are my summary notecards for the eight covered chapters of Broverman's Mathematics of Investment and Credit from the 2006 syllabus for Exam 2/FM. I hope someone finds this helpful!

I have all my written notes (prepared from Kellison's The Theory of Interest, now outdated) scanned into neat little PDF(s). I want to post them, but i was curious if i am violating any copyright laws since the notes follow the text quite closely and i have reproduced about half of his example problems in my notes. Any suggestions?

P.S. If i recall correctly, reprocessing/reproducing about a fifth of a copyright text without the intention of financial profit is permitted. But is its distribution then illegal? Heck, is posting the notes here a form of distribution?

Well, my notes that I previously posted follow the text very closely as well. If you're uncomfortable with posting them, or are wary of possible legal problems, then don't post them, no one will hold it against you.

This seems to be a great place for a short little helpful tidbit:

For Duration or Increasing annuities..., sometimes $a_{\overline{n|}$ is a lot easier to calculate (with a calculator for instance) than $Ia_{\overline{n|}$

$Ia_{\overline{n|}i} = (1+i)\frac{d}{di}P = (1+i)\frac{a_{\overline{n|}i+h}+(-1)a_{\overline{n|}i-h}}{2h}$

Note: the approximation is probably a faster way of calculating duration of a bond. Just punch in the initial values into the calculator (PMT, FV, I, N) and solve for PV with I, I+1, I-1 and then apply the above equation:
$Macaulay Duration = (1+i)\frac{\frac{d}{di}P}{P} = (1+i)\frac{a_{\overline{n|}i+h}+(-1)a_{\overline{n|}i-h}}{2ha_{\overline{n|}i}}$

eg. 30 year 80-coupon bond @ 6% yield:
$PV_{6%} = 1275.296623$
$PV_{5%} = 1461.173531$
$PV_{7%} = 1124.090412$
$(1.06)\frac{1461-1124}{0.02*1275} = 14.00$ (exact = 13.89)

If you have to solve for n or i this probably wont be useful...
