In mathematics,, a real number is a value of a continuous quantity that can represent a distance along a line (or alternatively, a quantity that can be represented as an infinite decimal expansion).The adjective real in this context was introduced in the 17th century by René Descartes, who distinguished between real and imaginary roots of polynomials.The real numbers include all the rational ...

: this is a capital sigma, the eighteenth letter of the Greek alphabet. It is not an ‘,E,’! Sigma corresponds to the English letter ‘S’; ‘S’ is for ‘sum’. k: The k on the left side of the equals is ,called, the index variable or the index of summation, or sometimes just the index.

The members of a set are ,called, its elements. In the set {1, 3, 5, 7, 9}, the numbers 1, 3, 5, 7, 9 are ,called, members of the set or more precisely elements of the set {1, 3, 5, 7, 9} The symbol ‘ ∈ ’ denotes ‘belongs to’ or it stands for ‘element of’.

in math,, ln means natural log, or loge and ,e, means 2.718281828 Why did they ,call, it pi in a ,math,? Well, it's because we like pie.Besides, look at 3.14 backwards.

See what basic ,math, looks like with our representation below. At home, you may for instance have a budget to help manage your income and probably put some money aside. If your monthly income is 1000 dollars, 50% may go to your rent or mortgage; 20% may go to food, clothing,gas, and other utilities; 20% may be used for personal items, gifts, and entertainment; finally, the remaining will go to ...

Matrix, a set of numbers arranged in rows and columns so as to form a rectangular array. The numbers are ,called, the elements, or entries, of the matrix. Matrices have wide applications in engineering, physics, economics, and statistics as well as in various branches of ,mathematics,.Historically, it was not the matrix but a certain number associated with a square array of numbers ,called, the ...

The equation expresses compounding interest as the number of times compounded approaches infinity. With the binomial theorem, he proved this limit we would later ,call e,.. We can actually follow the history of ,e, even further back than Bernoulli. It turns out that ,e, is the base for natural logarithms, and since these were studied extensively by John Napier one hundred years before Euler—in ...

In probability theory, the expected value of a random variable, denoted () or [], is a generalization of the weighted average, and is intuitively the arithmetic mean of a large number of independent realizations of .The expected value is also known as the expectation, mathematical expectation, mean, average, or first moment.Expected value is a key concept in economics, finance, and many other ...

If you mean [,math,]\exists[/,math,], it is read as “there exists”. For example: [,math,]\exists n \in \mathbb{N} : n^2 = n[/,math,] means “there exists a natural number [,math,]n[/,math,] such that [,math,]n[/,math,] is equal to its own square”. A related symbol...

13/12/2010, · The mark found above the "6" on a standard keyboard is ,called, a "caret". There are lots of different things the symbol is used for, but ,in mathematics, it's typically used to denote exponents. For example, 3^5 is three to the fifth power, 3*3*3*3*3 = 243. This is handy when you're using a format where you can't type superscripts.

Sequences and series are most useful when there is a formula for their terms. For instance, if the formula for the terms a n of a sequence is defined as "a n = 2n + 3", then you can find the value of any term by plugging the value of n into the formula. For instance, a 8 = 2(8) + 3 = 16 + 3 = 19.In words, "a n = 2n + 3" can be read as "the n-th term is given by two-enn plus three".
