Backwards 3 is a lowercase Greek letter called “EPSILON,” used for different purposes in social platforms and physical sciences.In physics, it is used for permittivity in a different medium.In mathematics, it is mainly used in “SETS,” which means “Belongs To.”For example: If A= [0, 1, 2, 3, 4, 5], then we can say 5 Ɛ…

It is the first letter in the Greek alphabet. It is derived from the word “ALEPH,” which means “ox” in Phoenician. It is written as “A” in uppercase and “α” in lowercase letters. It is mainly used in mathematics and sciences. It is also used for the beginning because it is the first letter of…

Ohm is the 24th and last letter in the Greek alphabet. It is used in physics to represent system international (SI) unit of electrical resistance. It is written in lowercase omega “Ω“.Ohm is discovered from the name of the scientist George ohm to describe the relationship between voltage, current, and resistance in electronics. Despite the…

Micro is the 12th letter of the Greek alphabet (U+00B5) which is primarily used in physics. Some of the quantities are very large or small, so we use prefixes to express these quantities. It is also a prefix that is useful to express very small quantities. Its value is (0.00001).For example, if you have a…

It is a fourth Greek letter that is used for different purposes. In mathematics, it is used for CHANGE in something. It is also used to represent the area of triangles. In physics, it is used for the difference between two points. For example, ΔT=T2-T1  (Here T is temperature). Types of Delta: It can be written in two forms:…

In mathematics, It is used in geometry to represent the straight line that passes through the centre of the circles. There are two types of diameter symbol: Uppercase sign (Ø) and lowercase sign (ø). Dia signs cannot be inserted through a keyboard like brackets, percentage, micro, or pipe symbol, and other symbols. Here we discuss…

A Russian backwards R symbol is the Russian language’s 33rd and last letter. It is pronounced as “Ya” in Russian.The keyboard has no built-in key to insert “Ya” like an inverted 3, but you can still insert it by keyboard shortcuts and Alt code. It is also available in the symbol library in word, excel,…

It is the 18th letter in the Greek alphabet. It is written as “Σ” in uppercase and “σ” in lowercase letters. Uppercase sigma also called summation used in mathematics to sum numbers for a given range and lowercase sigma is called standard deviation. As some of the symbols are available on the keyboard like pipe…

An approximately equal symbol is used in mathematics to show that the two quantities are not the same but nearly equal to each other. On the keyboard, we have different special characters including the backslash key, vertical bar key, and hash sign but unfortunately, we don’t have almost equal to sign. In Microsoft Windows or…

The number which is written as two integers separated by the symbol “/” (also known as “divide” or “by”) and expressed as one integer above and one integer below is called a fraction. Although Mac and Windows keyboards lack the one-half symbol, you can still enter it using alt codes. Use the half alt code…
