WebMar 15, 2024 · Can the cross product be negative? The cross product of two vectors is a vector itself. When we find the cross product of two unit vectors, then the magnitude of the resultant vector is sine and hence always positive. But in the case of a dot product of two unit vectors the resultant vector is cosine, that can be negative or positive.
