The dot product of two vectors is calculated by multiplying their corresponding components and adding the results. Here, $v = -4i$ and $w = j$, which means $v$ has components $(-4, 0)$ and $w$ has components $(0, 1)$. The dot product is $(-4 \times 0) + (0 \times 1) = 0$.

Find the Dot Product V · W v=−4i,w=jv = - 4 i , \quad w = jv=−4i,w=j

Find the Dot Product V · W $v = - 4 i , \quad w = j$
