Dot Operator Symbol (⋅)
The dot operator symbol is used in math to represent multiplication and, in the context of linear algebra, as the dot product operator. Typically, the symbol is used in an expression like this: 3⋅ 5. In plain language, this expression means three multiplied by five.
Dot product - Wikipedia
In physics, the dot product takes two vectors and returns a scalar quantity. It is also known as the "scalar product". The dot product of two vectors can be defined as the product of the magnitudes of the two vectors and the cosine of the angle between the two vectors.
The "Dot Operator (⋅)" Symbol in Mathematics
The Dot Operator, symbolized as ⋅ is a mathematical notation frequently employed in various mathematical contexts. One of its primary usages is in vector calculus, where it represents the dot product. Additionally, it can denote multiplication in some scenarios, especially when traditional multiplication signs might be confusing.
Dot Product - Math is Fun
They can be multiplied using the " Dot Product " (also see Cross Product). Calculating. The Dot Product is written using a central dot: a · b. This means the Dot Product of a and b. We can calculate the Dot Product of two vectors this way: a · b = | a | × | b | × cos (θ) Where: | a | is the magnitude (length) of vector a.

Aug 17, 2024 · We have already learned how to add and subtract vectors. In this chapter, we investigate two types of vector multiplication. The first type of vector multiplication is called the dot product, based on the notation we use for it, and it is defined as follows:
Multiplication sign - Wikipedia
In some countries, such as Germany, the primary symbol for multiplication is the "dot operator" ⋅ (as in a⋅b). This symbol is also used in compound units of measurement, e.g., N⋅m (see International System of Units#Lexicographic conventions).
Dot Product - Formula, Examples | Dot Product of Two Vectors
The dot product or the scalar product of two vectors is a way to multiply two vectors. Geometrically, the dot product is the product of the length of the vectors with the cosine angle between them. → a ⋅→ b a → ⋅ b → = |→ a|→ b| | a → | b …
