Napierian Logarithm
Write a number 
as
then
is the Napierian logarithm of . This was the original definition of a Logarithm, and can begiven in terms of the modern Logarithm as
The Napierian logarithm decreases with increasing numbers and does not satisfy many of the fundamental properties of themodern Logarithm, e.g.,
- Inverse Semigroup
- Inverse Sine
- Inverse Tangent
- Inverse Trigonometric Functions
- Inversion
- Inversion Center
- Inversion Circle
- Inversion Operation
- Inversion Radius
- Inversive Distance
- Inversive Geometry
- Inverted Funnel
- Inverted Snub Dodecadodecahedron
- Invertible Knot
- Involuntary
- Involute
- Involution (Group)
- Involution (Line)
- Involution (Operator)
- Involution (Set)
