BOB for Exponents and Logarithm

About this unit, i think there are some thing that we need to remember:

- A LOGARITHM IS AN EXPONENT. (Mr.K always says that we're going to forget that!!)

- The product law : log_bAB = log_bA + log_bB


- The quotient law : log_bA/B = log_bA - log_bB

- The power law : log_bC^k = k(log_bC)


- The change of base law:

- The exponential function : f(x) = e^x


- The natural logarithm : f(x) = ln(x)


About the formulas:

- A = P(1+r/n)^tn

- A = Pe<sup>rt

-</sup> A = A₀(m)<sup>t

-</sup> A = A₀(m)<sup>t/p

I wasn't in class for a last few days so i'm not sure if this is enough, but i think i kind of get it now even though i got some confused at first. Anyway, GOOD LUCK to every one. ^^</sup>
