What does the subscript 1 mean?

A small letter or number placed slightly lower than the normal text. Examples: • the number 1 here: A1 (pronounced “A sub 1” or just “A 1”) • the letter m here: xm (pronounced “x sub m” or just “x m”) Often used when we have a list of values.

What does a superscript 2 mean?

A small letter or number placed slightly higher than the normal text. Usually means how many times to use the value in a multiplication (also called an “exponent” or “power”). Examples: • the number 2 here: A2 (meaning A squared)

What does a subscript 0 mean?

Commonly, variables with a zero in the subscript are referred to as the variable name followed by “nought” (e.g. v0 would be read, “v-nought”). Subscripts are often used to refer to members of a mathematical sequence or set or elements of a vector.

What does the double lines mean in geometry?

Tick marks (shown in orange) indicate sides of a shape that have equal length (sides of a shape that are congruent or that match). The single lines show that the two vertical lines are the same length while the double lines show that the two diagonal lines are the same length.

What do you mean by subscript and superscript?

A superscript or subscript is a number, figure, symbol, or indicator that is smaller than the normal line of type and is set slightly above it (superscript) or below it (subscript).

What is the difference between superscript and subscript explain with an example?

Subscript is the text which a small letter/number is written after a particular letter/number. Superscript is the small letter / number above a particular letter / number. An example of superscript is 25. The number 5 above the number 2 is an example of superscript.

What do you mean by superscript and subscript?

What does bars mean in math?

Using bar notation, which is a way to show repeating numbers after a decimal point, is easier than writing the same repeating number and over again. It shows that the number pattern goes on for infinity, or forever. Bar notation can only be used after the decimal point.

What do the double bars mean in linear algebra?

Double bars (or sometimes even single bars) tend to denote a norm in Mathematics. Most likely, the double bars here are denoting the Euclidean norm. This is just the length of the vector. So for example, the vector (I shall write it horizontally for compactness) (1,2,3) has length ‖(1,2,3)‖=√12+22+32=√14.

What does the subscript p mean in normals?

As mentioned in the comments, the subscript p refers to the degree of the norm. Other commonly used norms are for p = 0, p = 1 and p = ∞. For p = 0 one gets the number of non-zero elements in x, for p = 1 (ie. ‖x‖1) one gets the Manhattan norm and for p = ∞ one gets the maximum absolute value from the elements in x.

What are the codes for superscript characters?

Codes for Superscript Characters Character Name Character Num Entity Hex Entity SUPERSCRIPT ZERO ⁰ &‌#8304; &‌#x2070; SUPERSCRIPT ONE Entity Code = ¹ ¹ &‌#185; &‌#x00B9; SUPERSCRIPT TWO Entity Code = ² ² &‌#178; &‌#x00B2; SUPERSCRIPT THREE Entity Code = ³ ³ &‌#179; &‌#x00B3;

What is the difference between superscripts and subscripts?

Superscripts and subscripts are often used to describe covariant and contra variant tensor indices in advanced physics. There’s a subtle difference between those two but don’t worry about that for now…. Rμν − 0.5Rgμν = 8πGTμν . the μν are two separate subscript indices though doesn’t show well in my cut and paste. These represent tensor indices.

What does the subscript “+” mean in a cubic polynomial?

Here, the subscript “+” implies taking the positive sign in the ratio on the right-hand side. In case of a cubic polynomial with all distinct roots, there can either be exactly one real root or exactly three real roots. The subscript “0” can be attached to the real root in the former case, and the middle of the three roots in the latter.
