Basis and dimension


A linear combination of two vectors is defined as follows. If[Equation goes here - download the original to see it.]and[Equation goes here - download the original to see it.]are two vectors of the vector space V then any vector of the form[Equation goes here - download the original to see it.]where[Equation goes here - download the original to see it.]is called a linear combination of[Equation goes here - download the original to see it.]and[Equation goes here - download the original to see it.]. A linear combination of vectors[Equation goes here - download the original to see it.]takes the form [Equation goes here - download the original to see it.] where [Equation goes here - download the original to see it.] Example [Equation goes here - download the original to see it.] Solution [Equation goes here - download the original to see it.]
