No. This is called the "cross product" or "vector product". Where the result of a dot product is a number, the result of a cross product is a vector. The result vector is perpendicular to both the other vectors. This means that if you have 2 vectors in the XY plane, then their cross product will be a vector on the Z axis in 3 dimensional space.Difference between cross product and dot product. 1. The main attribute that separates both operations by definition is that a dot product is the product of the magnitude of vectors and the cosine of the angles between them whereas a cross product is the product of magnitude of vectors and the sine of the angles between them. 2.The specific case of the inner product in Euclidean space, the dot product gives the product of the magnitude of two vectors and the cosine of the angle between them.
