In linguistics, diaeresis, diæresis or dieresis, is the pronunciation of two adjacent vowels in two separate syllables rather than as a diphthong or vowel digraph, and also the name of the diacritic mark ( ¨ ) used to prompt the reader to pronounce adjacent vowels in this manner. For example the first two vowels in the word cooperate, which can be spelt co-operate or, using the diaeresis, coöperate.
It depends on the language. In most languages, it's to indicate that the a should NOT be combined with the adjacent vowel, but pronounced in a separate syllable. In German, however, it changes the sound of the vowel itself. (Specifically, on the letter a, it means it should be pronounced as "ay" instead of the usual "ah".)
A colon consists of two dots, one directly over the other, and it looks exactly like this :
There are two vowel sounds that can be considered a schwa in algebra (ahl-juh-bruh), the E and the second A.
Compare the distance to a known length. Measure. If you know the coordinates of the two dots in an orthogonal coordinate system, use Pythagoras' theorem to find the distance. Say point 1 has coordinate (Ax,By) and point 2 has coordinate (Cx,Dy) then the distance between 1 and 2 is the square root of ((C-A)2 + (D-B)2))
Yes. The original denominator and its conjugate will form the factors of a Difference of Two Squares (DOTS) and that will rationalise the denominator but only if the radicals are SQUARE roots.
dieresis
Two dots over a vowel is normally called a dieresis. There is a special case of the dieresis in German where the two dots cause the vowel to change (sound and meaning): this special case is called umlaut.
Such marks, known as 'umlaut', are normally only used over vowels, to indicate a different vowel sound. Your question may need further clarification
The dots over i and j are called tittles. This is what wikipedia says:The tittle first appeared in Latin manuscripts in the 11th century, to distinguish the letter i from strokes of nearby letters. Although originally a larger mark, it was reduced to a dot when Roman-style typefaces were introduced.The 'u' or 'j' with two dots over are used in some languages,hungarian, Portuguese, to represent a different vowel sound to the English sound.I think they represent a vowel that is more 'fronted' than the English vowel.
It is known as an umlauts. It is not used in English, but is used over a vowel, especially in German, to indicate a different vowel quality.
It depends on what langauge you are talking about. If you mean German: ä: pronounce it like the "a" in ham ö: pronounce it like the "ur" in murder ü: has no equivalent in English but can be described as pronouncing the sound ee with rounded lips. If you mean Russian: ё: pronounced like "yo" or "oh" If you mean French: vowels with two dots above them do not change in pronunciation. The dots just mean that the vowel is separate from the previous vowel, such as naïve.
The double dot diacritical mark is a dieresis. In German it's an umlaut.
The two dots above a letter, you mean, would be called a diaeresis and/or an umlaut.
Depending on how it is used, a dot over a "T", used in a prescription order, could mean 1, such as 1 tablet/pill.... 1 time daily.
Do you mean, one dot above two dots? If that's what you intended, it means "therefore." I don't think ever seen two dots above one dot... wikipedia article on this: http://en.wikipedia.org/wiki/Therefore_sign
10 is two lines 11 is one dot over two lines 12 is two dots over two lines etc... 20 is one dot over a shell. 21 is one dot over one dot 22 is one dot over two dots etc... 39 is one dot over four dots over three lines 40 is two dots over a shell 41 is two dots over one dot 42 is two dots over two dots etc... 60 is three dots over a shell etc... 80 is four dots over a shell etc... 100 is a line over a shell The Mayan number system is a base-20 system. A dot is 1, a line is 5, and up to 19 you can write in one "digit". As soon as the number increases over 20, it goes up into the second "digit" and you stack a dot (this time multiplied by 20) over a shell shape (worth zero). It's just like our number system, except our number system uses a base-10 system.
I think the two dots are an umlaut. In that cas it is pronunced as if there were an e after the a. 'Staer'
