Document Summary

P is the principle, or original, amount. M is the number of time the interest is compounded per year. N is the number of compounding periods per year. R is the interest rate in decimal. Use this formula when you know the value of our money in the future and want to save toward that amount by regular payments. Use this formula when we know our money in the present and we are paying it off in the future by regular payments. Vertical asymptotes: x = a is a va if. Horizontal asymptote: x = c is a ha if. If e(p) > 1 demand is elastic. If e(p) < 1 demand is inelastic. If e(p) = 1 there is unit elasticity, meaning revenue is maximized. The integral is convergent if the limit is a number. The integral is divergent if the limit is + or - in nity.
