The dimension of a vector space is the number of vectors in any basis for the space, i.e. the number of coordinates necessary to specify any vector. This notion of dimension (the cardinality of a basis) is often referred to as the Hamel dimension or algebraic dimension to distinguish it from other notions of dimension.This is a set of linearly independent vectors that can be used as building blocks to make any other vector in the space. Let's take a closer look at this, as well as the dimension of a vector ...Since {(1,2),(0,1)} is a basis of R2 we determine c 1,c 2 such that (a,b) = c 1(1,2)+c 2(0,1). That is a = c 1 b = 2c 1 +c 2. Solving this system, we see that c 1 = a and c 2 = b−2c 1 = b−2a. Therefore (a,b) = a(1,2)+(b−2a)(0,1). It follows that F(a,b) = aF(1,2)+(b−2a)F(0,1) = a(3,−1)+(b−2a)(2,1) = (3a,−a)+(2b−4a,b−2a) = (2b ...The dimension of a vector space is the number of vectors in any basis for the space, i.e. the number of coordinates necessary to specify any vector.
