Linear Dependency
I have a confusion, let's say we have three vectors a,b & c in 2-D space. a & b are linearly independent but c is dependent on a & b. Can't we represent whole 2-D space using a,b & c as (any vector V) V = x*a + y*b +0*c and hence a,b & c form basis. Then how can we say that basis are set of linearly independent vectors. Please tell me where I am going wrong.
