The argument of the logarithmic function has the unit hours.

Logarithmic functions are the only continuous isomorphisms between these groups.

For example, in the logarithmic function , the base is considered a parameter.

For example, consider the problem of differentiating a logarithmic function:

The restriction of the logarithmic function to N.

This results in a device where output voltage is a logarithmic function of the slider position.

Using the exponential instead of the logarithmic function, the equation can be written out like this :

Commonly used functional forms include the logarithmic function and the negative exponential function.

(also in the list of integrals of logarithmic functions).

Some functions, such as the exponential or logarithmic functions, can be transformed so that they are linear.

Surely any man who could compute the independent variables of logarithmic functions in his head could comfort a crying woman.

However, they did not formulate the notion of a function, or have knowledge of the exponential or logarithmic functions.

In 1729 Johann Poleni built a tractional device that enabled logarithmic functions to be drawn.

Exponential and logarithmic functions:

The name is not related to the mathematical logarithmic function: Instead, the machine is described by the four parameters , , and .

The response function of the image sensor is non-linear and similar to a logarithmic function, which makes the sensor suitable for high dynamic range imaging.

Most researchers nowadays accept that a power law is a more realistic relationship, or that a logarithmic function is just one of a family of possible functions.

Additional buttons for scientific and engineering (trigonometric and logarithmic functions), statistics and logic functions can be enabled as needed.

It thus makes sense to define the hyperbolic angle from P to an arbitrary point on the curve as a logarithmic function of the point's value of "x".

Moreover, because the logarithmic function log("x") grows very slowly for large "x", logarithmic scales are used to compress large-scale scientific data.

Scalar arguments to transcendental functions such as exponential, trigonometric and logarithmic functions, or to inhomogeneous polynomials, must be dimensionless quantities.

The function definition can be a simple value, or a complicated function that includes trigonometric and logarithmic functions, and a one-, two-, or three-dimensional table lookup.

The function that assigns to y its logarithm is called logarithm function or logarithmic function (or just logarithm).

Mechanical special-purpose computers known as difference engines were proposed in the 19th century to tabulate polynomial approximations of logarithmic functions - i.e. to compute large logarithmic tables.

Other examples of nonlinear functions include exponential functions, logarithmic functions, trigonometric functions, power functions, Gaussian function, and Lorenz curves.
