In mathematics, the dot product or scalar product is an algebraic operation that takes two equal length sequences of numbers (usually coordinate vectors) and returns a single number.
Dot Product Math Is Fun
Dot Product A vector has magnitude (how long it is) and direction: Here are two vectors: They can be multiplied using the "Dot Product" (also see Cross Product).

Properties of Dot Product. Dot product is mutative − a →. b → = b →. a → (each equal to abcos θ) Dot product is Distributive. a →.(b → c →) = a →. b → a →. c → Associative property is not applicable to dot product. Same rules can be used on coordinate axis unit vectors, î, ĵ and k̂. î.î = ĵ.ĵ = k̂. k̂= 1. When a unit vector is multiplied to itself in dot product fashion, the result is always 1.

Dot product of two vectors ā and b is basically a scalar quantity that is equal to the sum of pair wise products of coordinate vectors a and b. Dot product is also known as scalar product or inner product .

Vector Calculus: Understanding the Dot Product ...
When dealing with vectors ("directional growth"), there's a few operations we can do: Add vectors: Accumulate the growth contained in several vectors. Multiply by a constant: Make an existing vector stronger (in the same direction). Dot product: Apply the directional growth of one vector to another. The result is how much stronger we've made the original vector (positive, negative, or zero).

where is the angle between the vectors and is the norm. It follows immediately that if is perpendicular to . The dot product therefore has the geometric interpretation as the length of the projection of onto the unit vector when the two vectors are placed so that their tails coincide.

Derivation of the component formula for the dot product, starting with its geometric definition based on projection of vectors.
In mathematics and vector algebra, the cross product or vector product (occasionally directed area product to emphasize the geometric significance) is a binary operation on two vectors in three dimensional space and is denoted by the symbol ×.
