I had an 'A' average in Heat Transfer going into the final. I had a boundary value problem to solve using a C++. I suck at programming. I spent weeks on it, time in the office with the professor. Program never worked, ended up with a 'C' for the course. I wasn't angry until later found out that at least half the class downloaded the code from the Internet and had the assignment done in an hour. Luke, there is value is recognizing when one is beating one's head on the wall for no benefit. Since I didn't actually answer the second question, you still have work to do....
Real annuities are insurance products and not really investments. When you die, the annuity money usually disappears. With insurance companies, there is pretty much always "a catch".
I've been taught to run away as fast as possible whenever someone brings up annuities as an investment option. I've been told that newer annuities have better terms but still not convinced. If anyone has good advice on where to stick post tax investments for a low risk with high return I am all ears.

Cool, I appreciate the advice, boss. I've spent two weeks on programming projects before too, only to not do so hot on it. Granted I feel I learned a lot from it. Im still cracking on that second formula haha.
For the record, our objective (ours, being students in my class) isnt to derive these formulas. We just need them for a piece of the project. They are unrelated to the course at hand. The professor said we can acquire them by any means necessary, so we can learn to use our resources. I figured Id use good old GBodyForum as a resource lol, among many others.
I'm in nearly 100% cash, now. There are some bluechip stocks with serious underlying problems and I'm waiting for their bubbles to burst. I'll give up the 5-10% short term gain now to avoid the coming 30% loss, then buy in. I can't think of one thing I would buy and hold now.
Back in the day I put all of my money in classic american Muscle Cars, but made the mistake of selling when the prices doubled and tripled. I should have waited 3 more years for the 5X ROI.
For the second equation, I think it is of the form:
A*exp(rt) - D*exp(r(t-1)) - D*exp(r(t-2)) - ....
Where
A = initial principal
r = rate
t = expected length of deduction
D = amount deducted per period t
My thinking is that the first term represents how much the principal would be worth in "t", and the following terms represent how much less the principal is worth because of the deductions plus the interest you're losing because of those deductions ... I don't feel like walking the 3 feet to the bookcase with all my old math textbooks to relearn the rules of simplifying equations with natural-log so you're on your own for that one
... incidentally, is this a Java class or a programming class? It sounds to me that the goal of the project is more setting-up a user interface that works rather than "figure out the math" so there would've been nothing wrong with the instructor providing the equations, in the absence of you'd probably be within your rights to design a killer interface with a bunch of iterative loops in the background
For those who'd like to research the matter, I recommend the film The Wrong Box (1966) with Michael Caine, Dudley Moore, Peter Sellers, Peter Cook, and a bunch of other big names of the day
And on a remotely related note, I am re-reading an old college textbook called the 'Medieval Machine'. by Jean Gampel, 1976. His thesis was that there was an industrial revolution in the middle ages. The switch from people to oxen and horses for farming, water and wind mills to do labor-intensive jobs like grinding grain and forging steel, the development of a professional class of workers in mining and masonry construction; the destruction of forests to make charcoal to make lime and smelt iron. And of course an early instance of the passive investor class making a bunch of money off of poor schmucks like us working a daily wage in a textile mill or mineshaft. The gripes we read about in the news today are not new.

A programming class, but we focus on Java. I took a Java class in high school, I learned Python in the Fall predominantly, and we dove a little into Matlab and UNIX in Fall as well. Thanks for that formula by the way.
Last night at class he ended up telling us what .jar files to search up on the internet that have the functions premade, so all we have to do is call them. I think two kids in the class of 60 got the exact correct formulas out of the million versions of the payment, future value, present vale, etc functions.
You learn more when you do your own research and I'm sure when his educator said to use your resources to find the answers never meant to get the answers from members of a forum. Half the battle is to learn your resources so you know where to find the answer to any particular issue.
