The logarithm function. If you specifically mean the function ex, the inverse function is the natural logarithm. However, functions with bases other than "e" might also be called exponential functions.

The main disadvantage is that there is no general analytical way of finding the logarithm of a number.

When a function is nested inside another function, the outer one is the parent, the inner is the child.

It is because the logarithm function is strictly monotonic.

The inverse function of the exponential is the logarithm.

The parent function of the exponential function is ax

That refers to the logarithm function. Since the base is not specified, the meaning is not entirely clear; it may or may not refer to the logarithm base 10.

The main disadvantage is that there is no general analytical way of finding the logarithm of a number.

It turns out that many calculations and formulae are simpler if natural logarithms are used. To give but one example, the derivative (or slope) of the nagural logarithm function is 1/x. This means the derivative of other logarithms is more complicated.

LN is typically the syntax used to represent the natural logarithm function. Although some programming languages and computer applications use LOG to represent this function, most calculators and math textbooks use LN. In use, it would look like this:y=ln(x)Which reads as "y equals the natural logarithm of x".The natural logarithm is a logarithm that has a base of e, Euler's number, which is a mathematical constant represented by a lowercase italic e (similar to how pi is a constant represented by a symbol). Euler's number is approximately equal to 2.718281, although it continues on far past six decimal places.Functionally, the natural logarithm can be used to solve exponential equations and is very useful in differentiating functions that are raised to another function. Typically, when the solution to an equation calls for the trivial use of a logarithm (that is the logarithm is only being used as a tool to rewrite the equation), either the natural logarithm or the common logarithm (base 10) is used.
