So, if both parallel components point the same way, then they have the same sign and give a positive dot product, while; if one of those parallel components points opposite to the other, then their signs are different and the dot product becomes negative. The vector product of two vectors is a vector perpendicular to both of them. Its magnitude is obtained by multiplying their magnitudes by the sine of the angle between them. The direction of the vector product can be determined by the corkscrew right-hand rule. The vector product of two either parallel or antiparallel vectors vanishes.

The dot product of a Cartesian coordinate system of two vectors is commonly used in Euclidean geometry.The dot product, also known as the scalar product, is an algebraic function that yields a single integer from two equivalent sequences of numbers. The dot product of a Cartesian coordinate system of two vectors is commonly used in Euclidean geometry.The magnitude of the cross product is the same as the magnitude of one of them, multiplied by the component of one vector that is perpendicular to the other. If the vectors are parallel, no component is perpendicular to the other vector. Hence, the cross product is 0 although you can still find a perpendicular vector to both of these.
