##### Definition2.1.5

The linear combination of the vectors $$\vvec_1,\vvec_2,\ldots,\vvec_n$$ with scalars $$c_1,c_2,\ldots,c_n$$ is the vector

\begin{equation*} c_1\vvec_1 + c_2\vvec_2 + \ldots + c_n\vvec_n\text{.} \end{equation*}

The scalars $$c_1,c_2,\ldots,c_n$$ are called the weights of the linear combination.
