In this system, the number ten may be written as " A ", " T " or " X ", and the number eleven as " B " or " E " ( another common notation, introduced by Sir Isaac Pitman, is to use a rotated " 2 " for ten and a reversed " 3 " for eleven ).

In Light path notation global lighting the paths of the type L ( D | S ) corresponds * E.

A longitude is thus specified in sexagesimal notation as 23 ° 27 ′ 30 " E. For higher precision, the seconds are specified with a decimal fraction.

An alternative representation uses degrees and minutes, where parts of a minute are expressed in decimal notation with a fraction, thus: 23 ° 27. 500 ′ E. Degrees may also be expressed as a decimal fraction: 23. 45833 ° E. For calculations, the angular measure may be converted to radians, so longitude may also be expressed in this manner as a signed fraction of π ( pi ), or an unsigned fraction of 2π.

Another style of notation, rarely used in English, uses the suffix " is " to indicate a sharp and " es " ( only " s " after A and E ) for a flat, e. g. Fis for F, Ges for G, Es for E. This system first arose in Germany and is used in almost all European countries whose main language is not English or a Romance language.

Isaac Barrow and Baermann used the notation Q. E. A., for " quod est absurdum " (" which is absurd "), along the lines of Q. E. D., but this notation is rarely used today.

If the center is a distinguished point considered as origin of E, as in a normed space, it is not mentioned in the definition and notation.

** 1 E + 9 m < sup > 2 </ sup > in scientific notation

** 1 E + 6 m < sup > 2 </ sup > or 10 < sup > 6 </ sup > m < sup > 2 </ sup > in scientific notation

The publication in 1901 of E. B. Wilson's textbook Vector Analysis, based on Gibbs's lectures at Yale, did much to propagate the use of vectorial methods and notation in both mathematics and theoretical physics, definitively displacing the quaternions that had until then been dominant in the scientific literature.

: 1. 125 2 < sup > 3 </ sup > ( using decimal representation ), or, in E notation,

It typically ranges between the F below middle C ( F < sub > 3 </ sub > in scientific pitch notation ) to the second G above middle C ( G < sub > 5 </ sub >), although at the extremes some voices can reach the E below middle C ( E < sub > 3 </ sub >) or the second B above middle C ( B < sub > 5 </ sub >).

The horizontal levels are denoted by capital letters A through E. Ranks and files of a level are denoted using algebraic notation.

where E is the expected value operator, cov means covariance, and, corr a widely used alternative notation for Pearson's correlation.

where the integral runs over the whole spectrum of H. The notation suggests that H is diagonalized by the eigenvectors Ψ < sub > E </ sub >.

The alto horn is an E transposing instrument written a major sixth above concert pitch: the alto horn notation for middle C represents the E below middle C in concert pitch.

In an alternate notation for block designs, an S ( t, k, n ) would be a t -( n, k, 1 ) design.

Ballard's notation is ( t, p, m ) where m is a multiple of the fractional offset between planes.

Using this notation, P ( t ) takes the form,

Imagine that the action I defined above is invariant under small perturbations ( warpings ) of the time variable t and the generalized coordinates q ; in a notation commonly used in physics,

where H is the Heaviside step function – the notation "" is to emphasize that u is a parameter ( fixed in any instance – the time when the cash flow will occur ), while t is a variable ( time ).

The “− i ” notation indicates that the vector y < sub >− i, t </ sub > may contain any of the y ’ s except for y < sub > it </ sub > ( since it is already present on the left-hand side ).

The notation below describes the relationship under the Galilean transformation between the coordinates and of a single arbitrary event, as measured in two coordinate systems S and S ', in uniform relative motion ( velocity v ) in their common directions, with their spatial origins coinciding at time t = t '= 0:

This potential confusion is because of expressing dates in a January-based ( Roman ) calendar ; a better notation would be something like 842t, the " t " standing for Tishri, indicating that the year crossed over into the two years 842 and 841 of the modern calendar.

It is the evolution function when the control inputs ( or source term, or forcing inputs ) are Heaviside functions: the notation emphasizes this concept showing H ( t ) as a subscript.

In signal processing the Hilbert transform of u ( t ) is commonly denoted by However, in mathematics, this notation is already extensively used

The question we will be interested in is: do the functions ( which are functions of the variable t we omitted in the notation ) converge to ƒ and in which sense?

as t tends to infinity ( see O notation ).

where the notation denotes the derivative of x with respect to t, for example.

The letter " d " is used, as is " t " to denote both " High G " and " D " grace notes, but an examination of the notation word, makes a mistake unlikely, thus " dieliu " means " F " with " high G " grace note, and then " high A " and " G ".

for every i, j, and t. The notation is explained below.

as rational function in t, evaluated at, with a complex variable in the usual Riemann zeta function notation.

No human being can write fast enough, or long enough, or small enough † ( †" smaller and smaller without limit ... you'd be trying to write on molecules, on atoms, on electrons ") to list all members of an enumerably infinite set by writing out their names, one after another, in some notation.

Algorithms can be expressed in many kinds of notation, including natural languages, pseudocode, flowcharts, programming languages or control tables ( processed by interpreters ).

The associative law can also be expressed in functional notation thus:.

Bra-ket notation can be used even if the vector space is not a Hilbert space.

Since virtually every calculation in quantum mechanics involves vectors and linear operators, it can involve, and often does involve, bra-ket notation.

* Given any combination of complex numbers, bras, kets, inner products, outer products, and / or linear operators, written in bra-ket notation, its Hermitian conjugate can be computed by reversing the order of the components, and taking the Hermitian conjugate of each.

Using summation notation, it can be written as

Since the elements can be uniquely sequenced by atomic number, conventionally from lowest to highest ( as in a periodic table ), sets of elements are sometimes specified by such notation as " through ", " beyond ", or " from ... through ", as in " through iron ", " beyond uranium ", or " from lanthanum through lutetium ".

Note that pure application of this method may provide only a partial ordering on the strings, since different strings can represent the same number ( as with " 2 " and " 2. 0 ", or when scientific notation is used, " 2e3 " and " 2000 ").

Decimal notation often refers to a base-10 positional notation such as the Hindu-Arabic numeral system ; however, it can also be used more generally to refer to non-positional systems such as Roman or Chinese numerals which are also based on powers of ten.

The alternative notation can be used to denote the equivalence class of the element specifically with respect to the equivalence relation.

This operation can be thought of ( very informally ) as the act of dividing the input set by the equivalence relation, hence both the name " quotient ", and the notation, which are both reminiscent of division.

Other types of notation are used in algebraic expressions when the required formatting is not available, or can not be implied, such as where only letters and symbols are available.

Often an abbreviated notation is used in which is interpreted directly as a random variable, but this can cause confusion.

This position is indicated separately in the internal representation, and floating-point representation can thus be thought of as a computer realization of scientific notation.

In common mathematical notation, the digit string can be of any length, and the location of the radix point is indicated by placing an explicit " point " character ( dot or comma ) there.

Since there is a lack of musical notation in early writings, the actual musical forms in the early church can only be surmised.

If the datum to be hashed is small enough, one can use the datum itself ( reinterpreted as an integer in binary notation ) as the hashed value.

One of the advantages of tab is that it can be easier for performers without formal training to learn, because the notation directly indicates where to play the note.

The superscript notation for inverses can sometimes be confused with other uses of superscripts, especially when dealing with trigonometric and hyperbolic functions.

Newton's notation for the derivative of acceleration can also be used, especially when " surge " or " lurch " is used instead of " jerk " or " jolt ".

In vector notation, this can be expressed as:

He showed that with a few simple operators and a notation for functions, one can build a Turing-complete language for algorithms.

As a result of differences in notation, history, use of enumeration, hierarchy, and facets, classification systems can differ in the following ways:
