The Formula

ln(x) = loge(x)

Natural Log, or ln(x), equals the base e logarithm of x.

Category	Range	Interpretation
Small	ln(x) < 1	The result is less than 1
Medium	1 <= ln(x) < 10	The result is between 1 and 10
Large	ln(x) >= 10	The result is equal to or greater than 10

Individual	Calculation	Result	Interpretation
John	ln(3)	1.098612	John’s result is a bit more than 1, which is pretty good.
Jane	ln(100)	4.605170	Jane’s result is larger. She is a “natural” at this!

Method	Advantage	Disadvantage	Accuracy Level
Calculator	Quick	Requires device	High
Logarithm Tables	No device needed	Slower	Medium
Estimation	No device needed	Can be inaccurate	Low

Year	Evolution
1614	Logarithms introduced by John Napier
1685	Natural logarithm concept introduced
2000s	Digital calculators widely available

Accuracy: Natural log calculations can have rounding errors.
Complex Numbers: Natural log of a negative number is a complex number, which can be confusing.
Large Inputs: Calculating the natural log of very large numbers can be difficult.

Method	Pros	Cons
Slide rule	No power needed	Less accurate
Abacus	Easy to use	Limited range

What is a natural log? A natural log, or ln(x), equals the base e logarithm of x.
What is the base of a natural log? The base of a natural log is the mathematical constant e, approximately equal to 2.71828.
How is a natural log calculated? A natural log is calculated as the base e logarithm of a number.
What is the natural log of 1? The natural log of 1 is 0.
Why is the natural log used? The natural log is used because it simplifies many calculations in mathematics and physics.
What does the natural log graph look like? The graph of the natural log function is a curve that starts at negative infinity when x is 0 and increases without bound as x goes to infinity.
What is the derivative of the natural log? The derivative of the natural log of x is 1/x.
What is the integral of the natural log? The integral of the natural log of x is x*ln(x) – x.
How to calculate the natural log without a calculator? You can calculate the natural log without a calculator by using a series expansion or logarithm tables.
What are the properties of the natural log? The natural log has several properties, such as ln(x*y) = ln(x) + ln(y) and ln(x/y) = ln(x) – ln(y).
