It's the number always represented by ' e ' . Among a lot of
other things, it's the base of "natural" logs.

What is the best definition of a variable?
Symbols used to represent unspecified numbers or values.
What are the applicaton of fourier series?
It can be used in function approximation, especially in physics and numerical analysis and system & signals. Actually, the essence is that the basis of series is orthorgonal.
Why we draw tangent in newton raphson method?
A line tangent to a curve, at a point, is the closest linear approximation to how the curve is "behaving" near that point. The tangent line is used to estimate values of the curve, near that point.
An example how logarithms are used to explain a real life occurance?
not sure exaclty what you asking, but if ur asking for an example of what logarithms are used for in real life, then there are a heaps of examples. briefly, some examples are banks use logarithmic functions to calculate the accumilation of interest in bank accounts over the years (eg. Interest = xyz^0.01k), engineers use it to determine how quick things dry/cool down, etc. if u want a proper algebratic example, here is newtons law of cooling which is: y=yi x e^-kt where: y - different between temprature of body and the constant temp of room yi - initial temprature difference of body and room e - eulers number (2.718...) t - time in mins k - constant for that particular body (usually what u are trying to find out in class tasks) using logarithms, newtons law can predict how how a body (such as cup of coffee) will be after any given period of time. This was the most practicle example i could think of ;) Nick
Equation for linear approximation?
The general equation for a linear approximation is f(x) ≈ f(x0) + f'(x0)(x-x0) where f(x0) is the value of the function at x0 and f'(x0) is the derivative at x0. This describes a tangent line used to approximate the function. In higher order functions, the same concept can be applied. f(x,y) ≈ f(x0,y0) + fx(x0,y0)(x-x0) + fy(x0,y0)(y-y0) where f(x0,y0) is the value of the function at (x0,y0), fx(x0,y0) is the partial derivative with respect to x at (x0,y0), and fy(x0,y0) is the partial derivative with respect to y at (x0,y0). This describes a tangent plane used to approximate a surface.
Why do you multiply or add logarithms when working with frequencies?
I have seen logarithms used with decibels, which are used to measure power or intensity; not with frequencies.
How are logarithms used in electrical engineering?
Electrical engineers use logarithms to work on signal Decay.
When does Exponents used to solve a math problem?
common logarithms, natural logarithms, monatary calculations, etc.
How are radio waves used in math?
Logarithms
What is Approximation for pi?
3.14 is the commonly used approximation
What should you include in a paper about Logarithms?
you should include the definition of logarithms how to solve logarithmic equations how they are used in applications of math and everyday life how to graph logarithms explain how logarithms are the inverses of exponential how to graph exponentials importance of exponential functions(growth and decay ex.) pandemics, population)
Why we always take base 10 in logarithm?
Actually we don't. Any number greater than 1 can be used; it need not even be a whole number. In computer science, the number 2 is often used as a base; in advanced math, the number "e" is often used - this number is approximately 2.71828..., and for theoretical reasons it is considered to be the most "natural" base for logarithms. In fact, the logarithms in base "e" are called "natural logarithms".
Which symbol is used with a variable to indicate to the script that you are reading the contents of that variable?
Which symbol is used with a variable to indicate to the script that you are reading the contents of that variable?
What is a n independent variable?
an independent variable is a figure usually shown as a letter that is used in the scientific theory. An independent variable is used in a hypothesized experiment in which this variable is unchanged and is used to effect the dependent variable somewhere in the experiment.
What fraction is sometimes used as an approximation of pi?
It is: 22/7
What is the value of 0.05555 divide by 0.0008601 if use logarithms to solve the problem?
64.5855
What are the practical applications of logarithms in the field of engineering science business and economics?
Logarithms were originally used to convert multiplications into additions and divisions into subtractions (plus some looking up in tables).To multiply 3456 by 6789Look up in table: log(3456) = 3.5386Look up in table: log(6789) = 3.8318add them together = 7.3704Look up in table: antilog(7.3704) = 107.3704 = 23460000So the only calculation is a simple addition at step 3.Logarithms were often used for approximate calculations (4 significant figures), but there were tables for more accurate work.Nowadays, though, it is easier to use calculators for multiplication and division.There is a whole class of problems where the solution involves logarithms. If the rate of change in a variable X is directly proportional to the quantity X, then the solution involves logarithms (or its inverse, exponents). Typical textbook examples include radioactive decay, simple chemical reactions, bacterial {or any uncontrolled] growth, compound interest.
