If a vector has zero magnitude, is it meaningful to call it a vector?
If a vector has zero magnitude in what sense it is a vector?
Why is it impossible for a vector to have a negative magnitude? How do you prove that every vector space contains a zero vector? Can anyone clear up my confusion as to how the zero vector is in Nul(A)? Aren't the vectors in Nul(A) the non-zero vectors that make some matrix A equal to 0? What is a vector quantity? What is a vector? WHAT is really a vector? Is it possible that the resultant of two vectors of equal magnitude has same magnitude as the two vectors have? Why is the null vector a vector? What is the physical significance of vector operator? What is the physical significance of vector space? How is displacement considered as a vector quantity? What is a vector in linear algebra? Can the sum of the magnitudes of two vectors ever be equal to the magnitude of the sum of the same two vectors? Can the components of a vector also be a vectors? If two vectors of equal magnitude add to either of them by magnitude what is the angle between them? Can eigen values and eigen vectors be zero? What is the physical significance of dimension of a vector space? I've seen vectors described as direction and magnitude, and also as a one dimensional matrix. Are these concepts somehow related, or merely homonyms? What is a vector machine? What is a vector divided by a vector? Find a vector whose magnitude is 7 and which is perpendicular to each vector A = 2i - 3j + 6k and vector B = i + j - k ? Is length a vector? What is vector design? What is a vector-valued random variable? Is power a vector quantity? How is this determined? What is 0 dimension? What is a vector space? What are the components of a vector? Is light a vector? What is the vector of a random variable?
