## How To Find The Dimension Of A Subspace

### 14/03/2014Â Â· U is set of vectors of the form (-3 b, b, 0, -2 a, -2 a - 2 b) What is the dimension of U? I understand I have to first find the basis, then count the number of vectors in the basis but it's hard to do so with such vectors above.

- The dimension of a vector space is the number of independent vectors required to span the space. Subspaces. N-dimensional space V n (F) has embedded in it subspaces of lesser dimensions.
