====Compound-Interest Formulas====
1. End Value of Initial sum after n years: V<sub>n</sub> = V<sub>o</sub>(1+r)<sup>n</sup> \\
2. Initial value of end value: V<sub>o</sub> = V<sub>n</sub>/(1+r)<sup>n</sup> \\
3. Rate of interest earned on sum: r=100[(V<sub>n</sub>/V<sub>o</sub>)<sup>1/n</sup>-1] \\
4. Amount of interest earned: R<sub>n</sub> = V<sub>o</sub>[(1+r)<sup>n</sup>-1]\\ 
5. Initial value of a perpetual annual payment: V<sub>o</sub> = a + a/r\\ 
6. Initial value of terminal series of annual payments: V<sub>o</sub> = a + a/r [((1+r)<sup>n</sup>-1)/(1+r)<sup>n</sup>]\\
7. End value of terminal series of annual payments: V<sub>n</sub> = a[(1+r)<sup>n</sup>-1] / r\\
8. Present worth of land: Present Worth = Net value at end of rotation/((1+r)<sup>t</sup>-1) \\
====Legend====
V<sub>n</sub> = end value\\
r = rate of interest\\
V<sub>o</sub> = initial value\\
R<sub>n</sub> = amount of interest ($)\\
n = number of years\\
a = annual payment\\
t = length of rotation\\
