the cross product is the multiplication of to vectors which results in another vector unlike the dot product witch equals a scalar

The dot-product and cross-product are used in high order physics and math when dealing with matrices or, for example, the properties of an electron (spin, orbit, etc.).
A vector rotation in math is done on a coordinate plane.2D vectors can be rotated using the cross and dot product.3D vectors are rotated using matrix based quaternion math.
The product in a math is the answer to a multiplication problem.
the math operation that is the product is the anwser.
The "product" is common in math problems. (Especially multipucation problems.) A product is the answer to a multipucation problem.
0 is a cross product of a vector itself
what is a defition
A product is the answer to a multiplication problem in math.
cross: torque dot: work
The derivative of the cross product with respect to a given variable is a vector that represents how the cross product changes as that variable changes.
The cross product can be said to be a measure of the 'perpendicularity' of the vectors in the product. Please see the link.
the more you multiply it the product becomes higher in math
