Use a change of variables to find the indefinite integral xe^(x^2) dx
ValentinkaMS [17]
\displaystyle\int xe^{x^2}\,\mathrm dx=\frac12\int2xe^{x^2}\,\mathrm dx

If we take y=x^2, then \mathrm dy=2x\,\mathrm dx, and we can write the above integral as


\displaystyle\frac12\int e^y\,\mathrm dy=\frac12e^y+C

and undoing the substitution, we end up with

\displaystyle\int xe^{x^2}\,\mathrm dx=\frac12e^{x^2}+C
