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
When a vowel has two dots over it (diaeresis), it indicates that the vowel is to be pronounced as a separate syllable rather than combined with the previous vowel. This is common in some languages, like German and Dutch, to show that the two vowels should be pronounced individually.
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.
Two dots above a vowel typically indicate that the vowel should be pronounced as a separate syllable or with a different sound. This diacritic mark is known as a diaeresis or umlaut, and it is commonly used in various languages such as German and Hungarian.
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.
The letter "ö" with two dots on top is called an umlaut. It is used in various languages such as German and Swedish to indicate a different pronunciation of the vowel. It can change the sound of the vowel and distinguish between different words or meanings.
The two dots above a letter, known as a diaeresis, indicate that the letter should be pronounced separately from the preceding vowel. This is common in languages like German and Dutch, where it affects the pronunciation of vowels.
A letter "u" with two dots above it is called an umlaut. In languages like German, it indicates a change in the pronunciation of the vowel, often making it sound as two separate vowels or modifying its sound.
The letter with two dots is called an umlaut and is pronounced by adding a "y" sound before the vowel. For example, "ü" is pronounced like "ue" in German.
The double dot diacritical mark is a dieresis. In German it's an umlaut.
Two dots (also called an umlaut) over the letter "ss" is not a standard diacritic mark in German or other languages. It is most likely a typographical error or a non-standard representation. The umlaut is usually placed over vowels in German to indicate a different pronunciation.
