# Arrow—Wolfram Language Documentation.

An arrow is a graphical symbol, such as ← or →, or a pictogram, used to point or indicate direction. In its simplest form, an arrow is a triangle, chevron, or concave kite, usually affixed to a line segment or rectangle, and in more complex forms a representation of an actual arrow e.g. U27B5. In Arrow [pt 1, pt 2, s] the setback distance s is measured in the ordinary coordinate system of the whole graphic, so that the arrow will just touch Disk [pt i, s]. » If the whole graphic does not have AspectRatio->Automatic, then a specified arrow setback may correspond to different distances in different directions in the graphic.

The Math Arrow is a learning tool that makes the relationship between numbers more intuitive, friendlier and easier for kids. It aligns numbers in a parallel zigzag design that allows children to detect patterns in the relationship of the numbers. When referring to mathematics, the word parallelism means not intersecting and being an equal distance apart everywhere. As an example parallelism is when one has two lines which are one above the other and they are an equal distance apart on both ends and do. arrowStart,Stop draws a line with an arrow from Start to Stop points should be vectors of length 2 or 3, or matrices with 2 or 3 columns, and returns the graphics handle of the arrows. Edit: @Lama is also right, you can use annotation but you need to take into account the plot limits. 30/09/2007 · it means to the power of the number preceding the arrow. 2^2=2x2=4. 2^4=2x2x2x2=16.

23/01/2011 · Think of it this way, the sign is a open mouth. This mouth is hungry for number and wants to eat the biggest number. So the greater number is going to have to mouth open towards it; the lesser number will have the mouth closed towards it. For example, this notation is used when linearizing equation, to show which higher order terms are ignored in the coming analysis.

Lots of these arrows are from math, but some are also used elsewhere. The problem is, it's hard to categorize them into one place. So, in Unicode, the arrows gets into one of these blocks: “Miscellaneous Mathematical Symbols-B”, “Supplemental Mathematical Operators”, “Miscellaneous Symbols and Arrows”. This is typically more well known as ‘Knuth’s Up-Arrow Notation’. It should be evident that [math]b[/math] in all of the below is assumed to be an integer, for the inductive definition can’t be carried out.

Mathematicians don’t often change the style of letters to denote special functions, but the Weierstrass ℘ function is a notable exception. The symbol is described in. Although the ethos of category theory is to define things externally to objects, when we are trying to get an intuitive understanding of the subject it helps to look at concrete categories and compare internal arrows between elements and external arrows between objects. So here we look at various types of arrow in finite set category.
