Logarithmic functions
This tutorial shows you what a logarithmic function is. It will then go on to show the many times in nature and science that these type of functions are useful to describe what is happening.

Compound Interest and e (part 2)
ccCompounding 100% annual interest continuously over a year converges to e (2.71...)
-
Compound Interest and e (part 3)
ccContinuously compounding $P in principal at an annual interest rate of r for a year ends up with a final payment of $Pe^r

Compound Interest and e (part 4)
ccContinuously compounding for multiple years.
Continuous compounding and e
This tutorial introduces us to one of the derivations (from finance and continuously compounding interest) of the irrational number 'e' which is roughly 2.71...
