The logarithmic function is the inverse function of exponentiation. Visit BYJU'S to learn the formulas, important properties and rules used in logarithms with examples.
logbeis a constant. Seechange of base ruleto see how to work out such constants on your calculator.) Note 1:This formula is derived fromfirst principles. Note 2:If we chooseeas the base, then the derivative oflnu,whereuis a function ofx, simply gives us our formula above: ...
Decimal logarithmic function is defined on positive part of the real axis — so its domain is (0, +∞). 0 is a singular point. Function graph is depicted below —fig. 1. Fig. 1.Graph of the decimal logarithmic functiony= logx. ...

The Natural Exponential Function Definition The inverse function of the natural logarithmic function f(x) = ln x is called the natural exponential function and is denoted by f -1 (x) = e x y = e x if and only if x = ln y ln(e x ) = x e lnx = x ...
The Logarithmic transform proposed by Reynolds and Stauffer [1] is used in this work and applied to a form of the Euler integral of the first kind and expressed in terms of the Lerch function. In the present work, the authors used their contour integral method and applied it to a special...
