A certain fluid with volume $0\mathrm{.}06m^3$ has expanded reversibly in a cylinder behind a pis according to a law $PV=0\mathrm{.}5$ to become $0\mathrm{.}09m^3,$ where $P$ is the pressure in $\frac{N}{m^2}$ and $V$ volume in $m^3.$ Find the work done $W={\displaystyle \underset{0\mathrm{.}06}{\overset{0\mathrm{.}09}{}}}PdV$ using composite Trapezoidal rule tak six equal parts. Also find out the associated absolute error of your estimation.
