The function $\displaystyle {w}{\left({t}\right)}$ is graphed below. Find the value of each of the following integrals based on the graph of $\displaystyle {w}{\left({t}\right)}$.

$\displaystyle {\int_{{0}}^{{3}}}{w}{\left({t}\right)}{\left.{d}{t}\right.}=$

$\displaystyle {\int_{{3}}^{{6}}}{w}{\left({t}\right)}{\left.{d}{t}\right.}=$

$\displaystyle {\int_{{0}}^{{6}}}{w}{\left({t}\right)}{\left.{d}{t}\right.}=$

$\displaystyle {\int_{{0}}^{{3}}}{w}{\left({t}\right)}{\left.{d}{t}\right.}+{\int_{{3}}^{{6}}}{w}{\left({t}\right)}{\left.{d}{t}\right.}=$

$\displaystyle {\int_{{3}}^{{3}}}{w}{\left({t}\right)}{\left.{d}{t}\right.}=$

$\displaystyle {\int_{{0}}^{{6}}}{w}{\left({t}\right)}{\left.{d}{t}\right.}-{\int_{{3}}^{{3}}}{w}{\left({t}\right)}{\left.{d}{t}\right.}=$

$\displaystyle {\int_{{6}}^{{3}}}{w}{\left({t}\right)}{\left.{d}{t}\right.}=$
