1/E^X - Ableiten der Exponentialfunktion

Dann folgt für die Ableitung. Über seinen Zusammenhang mit Bits und Bytes informiert der nebenstehene Button.

The argument of the exponential function can be any real or complex number , or even an entirely different kind of mathematical object e.

The ubiquitous occurrence of the exponential function in pure and applied mathematics has led mathematician W. Rudin to opine that the exponential function is "the most important function in mathematics".

This occurs widely in the natural and social sciences, as in a self-reproducing population , a fund accruing compound interest , or a growing body of manufacturing expertise.

Thus, the exponential function also appears in a variety of contexts within physics , chemistry , engineering , mathematical biology , and economics.

It is commonly defined by the following power series : [6] [7]. By way of the binomial theorem and the power series definition, the exponential function can also be defined as the following limit: [8] [7].

The exponential function arises whenever a quantity grows or decays at a rate proportional to its current value.

One such situation is continuously compounded interest , and in fact it was this observation that led Jacob Bernoulli in [9] to the number. Later, in , Johann Bernoulli studied the calculus of the exponential function.

Letting the number of time intervals per year grow without bound leads to the limit definition of the exponential function,.

From any of these definitions it can be shown that the exponential function obeys the basic exponentiation identity,.

The derivative rate of change of the exponential function is the exponential function itself. More generally, a function with a rate of change proportional to the function itself rather than equal to it is expressible in terms of the exponential function.

This function property leads to exponential growth or exponential decay. The exponential function extends to an entire function on the complex plane.

Euler's formula relates its values at purely imaginary arguments to trigonometric functions. The exponential function also has analogues for which the argument is a matrix , or even an element of a Banach algebra or a Lie algebra.

That is,. Functions of the form ce x for constant c are the only functions that are equal to their derivative by the Picard—Lindelöf theorem.

Other ways of saying the same thing include:. If a variable's growth or decay rate is proportional to its size—as is the case in unlimited population growth see Malthusian catastrophe , continuously compounded interest , or radioactive decay —then the variable can be written as a constant times an exponential function of time.

The constant k is called the decay constant , disintegration constant , [10] rate constant , [11] or transformation constant.

Furthermore, for any differentiable function f x , we find, by the chain rule :. A continued fraction for e x can be obtained via an identity of Euler :.

The following generalized continued fraction for e z converges more quickly: [13]. For example:. As in the real case, the exponential function can be defined on the complex plane in several equivalent forms.

The most common definition of the complex exponential function parallels the power series definition for real arguments, where the real variable is replaced by a complex one:.

Alternatively, the complex exponential function may defined by modelling the limit definition for real arguments, but with the real variable replaced by a complex one:.

For the power series definition, term-wise multiplication of two copies of this power series in the Cauchy sense, permitted by Mertens' theorem , shows that the defining multiplicative property of exponential functions continues to hold for all complex arguments:.

The definition of the complex exponential function in turn leads to the appropriate definitions extending the trigonometric functions to complex arguments.

In this expansion, the rearrangement of the terms into real and imaginary parts is justified by the absolute convergence of the series.

The real and imaginary parts of the above expression in fact correspond to the series expansions of cos t and sin t , respectively.

The functions exp , cos , and sin so defined have infinite radii of convergence by the ratio test and are therefore entire functions i.

Intuitively, the expectation of a random variable taking values in a countable set of outcomes is defined analogously as the weighted sum of the outcome values, where the weights correspond to the probabilities of realizing that value.

However, convergence issues associated with the infinite sum necessitate a more careful definition.

A rigorous definition first defines expectation of a non-negative random variable, and then adapts it to general random variables.

Unlike the finite case, the expectation here can be equal to infinity, if the infinite sum above increases without bound.

By definition,. A random variable that has the Cauchy distribution [11] has a density function, but the expected value is undefined since the distribution has large "tails".

The basic properties below and their names in bold replicate or follow immediately from those of Lebesgue integral. Note that the letters "a.

We have. Changing summation order, from row-by-row to column-by-column, gives us. The expectation of a random variable plays an important role in a variety of contexts.

For example, in decision theory , an agent making an optimal choice in the context of incomplete information is often assumed to maximize the expected value of their utility function.

For a different example, in statistics , where one seeks estimates for unknown parameters based on available data, the estimate itself is a random variable.

In such settings, a desirable criterion for a "good" estimator is that it is unbiased ; that is, the expected value of the estimate is equal to the true value of the underlying parameter.

It is possible to construct an expected value equal to the probability of an event, by taking the expectation of an indicator function that is one if the event has occurred and zero otherwise.

This relationship can be used to translate properties of expected values into properties of probabilities, e. The moments of some random variables can be used to specify their distributions, via their moment generating functions.

To empirically estimate the expected value of a random variable, one repeatedly measures observations of the variable and computes the arithmetic mean of the results.

If the expected value exists, this procedure estimates the true expected value in an unbiased manner and has the property of minimizing the sum of the squares of the residuals the sum of the squared differences between the observations and the estimate.

The law of large numbers demonstrates under fairly mild conditions that, as the size of the sample gets larger, the variance of this estimate gets smaller.

This property is often exploited in a wide variety of applications, including general problems of statistical estimation and machine learning , to estimate probabilistic quantities of interest via Monte Carlo methods , since most quantities of interest can be written in terms of expectation, e.

In classical mechanics , the center of mass is an analogous concept to expectation. For example, suppose X is a discrete random variable with values x i and corresponding probabilities p i.

Now consider a weightless rod on which are placed weights, at locations x i along the rod and having masses p i whose sum is one.

The point at which the rod balances is E[ X ]. Expected values can also be used to compute the variance , by means of the computational formula for the variance.

A very important application of the expectation value is in the field of quantum mechanics. Use parentheses, if necessary, e.

In " Examples" , you can see which functions are supported by the Integral Calculator and how to use them.

When you're done entering your function, click " Go! In " Options ", you can set the variable of integration and the integration bounds.

If you don't specify the bounds, only the antiderivative will be computed. Clicking an example enters it into the Integral Calculator.

Moving the mouse over it shows the text. The practice problem generator allows you to generate as many random exercises as you want. You find some configuration options and a proposed problem below.

You can accept it then it's input into the calculator or generate a new one. Not what you mean? Use parentheses! Set integration variable and bounds in " Options ".

First, a parser analyzes the mathematical function. It transforms it into a form that is better understandable by a computer, namely a tree see figure below.

In doing this, the Integral Calculator has to respect the order of operations. The Integral Calculator has to detect these cases and insert the multiplication sign.

The parser is implemented in JavaScript , based on the Shunting-yard algorithm , and can run directly in the browser. This allows for quick feedback while typing by transforming the tree into LaTeX code.

MathJax takes care of displaying it in the browser.
