Distinguish a logarithm from its absolute-value graph

(i) Find $\int\ln(2x-1)\,dx$.

(ii) Sketch $y=|\ln(2x-1)|$, stating asymptotes and axis intercepts.

(iii) Find the exact area bounded by $y=|\ln(2x-1)|$, the x-axis, $x=3/4$ and $x=3/2$.

(iv) Find the volume when the region bounded by $y=\ln(2x-1)$, the x-axis, $x=3/2$ and $x=3$ rotates completely about the y-axis.
