Vectors in R

This notebooks shows how to work with vectors in R

Given are the following two vectors \(v\) and \(w\). Compute

• the sum \(v+w\),
• the difference \(v-w\) and
• the dot product \(v\cdot w\).

\[v = \left[\begin{array}{c} 3 \\ -5 \\ 1 \\ 9 \\ \end{array}\right] \]

and

\[w = \left[\begin{array}{c} 1 \\ 9 \\ -12 \\ 27 \\ \end{array}\right] \]
