The compound interest formula for annual compounding is
A(P, r, t) = P(1 + r)t
Where A is the future value of an investment of P dollars after t years at an interest rate of r.
a. Calculate δA/δP, δA/δr, and δA/δt, all evaluated at (100, 0.10, 10). Round answers to 2 decimal places.
b. What does the function δA/δP│(100, 0.10, t) of t say about your investment?

In lecture, Professor Gruber explained discrete compounding interest. Interest can also be compounded continuously. Here we explain the difference. Professor Gruber calculated future value as FV = P(1+r)", where P is the principal, r is the interest rate, and t is the term of the contract (often in years). This formula can be generalized to FV = P(1+r/m)mt, where m is the number of compounding periods per year (in lecture, this was 1). That is, after every compounding period, more...

1. Using Python write a function for compounding interest. There should be three arguments to the function: a starting amount, a total interest rate, and the number of compounding periods. The function returns the ending value. Notes: normally, interest rates are given per period, or annually. The total interest rate would be the per-period interest rate multiplied by the number of compounding periods. Or in your function, the per-period interest added is the total rate divided by the number of...
