\int ln(x)dx
\int uv'=uv-\int u'v\rightarrow u=ln(x),u'=\frac{1}{x},v'=1,v=x
=ln(x)x-\int \frac{1}{x}xdx
=xln(x)-\int 1dx
\int 1dx=x
=xln(x)-x+C

\int xsin(x)dx
\int uv'=uv-\int u'v\rightarrow u=x,u'=1,v'=sin(x),v=-cos(x)
=x(-cos(x))-\int 1(-cos(x))dx
=-xcos(x)-\int -cos(x)dx
\int -cos(x)dx=-sin(x)
=-xcos(x)-(-sin(x))
sin(x)-xcos(x)+C
