What is e? Who first used e? How do you find it? How many digits is it? ... e is also the base of natural logarithms. The natural logarithm function ln(x) is defined that way: ln(x) = loge(x). This is "natural" for several reasons. One is the following limit...

For example, to calculate Log (100): if your calculator yields Ln(100) = 4.60517, then Log(100) = Ln(100)/2.303 = 4.60517/2.303 = 1.9996 (very close to exact answer of 2) ... Back to first slide ... View graphic version...
