The cross product only works in 3D. It takes two vectors as inputv1andv2, and returns a vectorc. The returned vector will be perpendicular to both the input vectors. The length of the vector is equal to the product of the lengths of the input vectors and the sine of the angle between...
Dot product. The dot product, also commonly known as the “scalar product” or “inner product”, takes two equal-length vectors, multiplies them together, and returns a single number. The dot product of two vectors a=[a1,a2,…,an] and b=[b1,b2,…,bn] is defined as a.b=∑i=1na...

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).CalculatingThe Dot Product is written using a central dot:a· b This means the Dot Product of a and b...
Given two vectors u and v, their cross product u × v is a vector perpendicular to u and v. The motivation for this property, however, is never addressed. Here we show that the existence of the cross and dot products and the perpendicularity property follow from the concept of linear ...

(or "cross product"). For simplicity, we will only address the scalar product, but at this point, you should have a sufficient mathematical foundation to understand the vector product as well. Thescalar product(ordot product) of two vectors is defined as follows in two dimensions. As always...
the quantity obtained by multiplying the corresponding coordinates of each of two vectors and adding the products, equal to the product of the magnitudes of the vectors and the cosine of the angle between them. Also calleddot product,scalar product. ...
