n mathematics, the logarithmic function is an inverse function to exponentiation. The logarithmic function is defined as The base of the logarithm is a. This can be read it as log base a of x. The most 2 common bases used in logarithmic functions are base 10 and base e.
A mapping diagram can be used to represent a function or a relation true or false?

The sign function is used to represent the absolute value of a number when used in trigonometry. It is also referred to as the signum function in math.

The pH scale is a logarithmic scale used to express the acidity or basicity of a solution. The formula to calculate pH is pH = -log[H+], where [H+] is the hydrogen ion concentration in moles per liter. This logarithmic equation allows for a convenient way to represent a wide range of hydrogen ion concentrations in a compact form.
ER diagrams often use symbols to represent three different types of information. Boxes are commonly used to represent entities. Diamonds are normally used to represent relationships and ovals are used to represent attributes.
The Heaviside function is a discontinuous step function. It is 0 for all values less than some specific value. At and after that value, it takes the value 1. The Heaviside function can be used to represent an "Off-On" function.See link for more.The Heaviside function is a discontinuous step function. It is 0 for all values less than some specific value.

The exponential function is e to the power x, where "x" is the variable, and "e" is approximately 2.718. (Instead of "e", some other number, greater than 1, may also be used - this might still be considered "an" exponential function.) The logarithmic function is the inverse function (the inverse of the exponential function).The exponential function, is the power function. In its simplest form, m^x is 1 (NOT x) multiplied by m x times. That is m^x = m*m*m*...*m where there are x lots of m.m is the base and x is the exponent (or power or index). The laws of indices allow the definition to be extended to negative, rational, irrational and even complex values for both m and x.There is a special value of m, the Euler number, e, which is a transcendental number which is approx 2.71828... [e is to calculus what pi is to geometry]. Although all functions of the form y = m^x are exponential functions, "the" exponential function is y = e^x.Finally, if y = e^x then x = ln(y): so x is the natural logarithm of y to the base e. As with the exponential functions, the logarithmic function function can have any positive base, but e and 10 are the commonly used one. Log(x), without any qualifying feature, is used to represent log to the base 10 while logx where is a suffixed number, is log to the base b.
An electronic device uses electric to represent coded information. Variations in the current are converted to codes used by the electronic device.
From a math point of view, a logarithmic scale is used when there is a great range of values. Common example are the Ph scale for acidity, decibels for noise, and the Richter scale for earthquakes.
