Solution. We want to determine the integral of xe^{x^2}, i.e.:
\begin{align*} \int xe^{x^2}dx. \end{align*}
\begin{align*} \int xe^{x^2}dx &= \frac{1}{2} \int e^u du \\ &= \frac{1}{2}e^u + C \\ &= \frac{1}{2}e^{x^2} + C. \end{align*}
\begin{align*} \int xe^{x^2}dx. \end{align*}
\begin{align*} \int xe^{x^2}dx &= \frac{1}{2} \int e^u du \\ &= \frac{1}{2}e^u + C \\ &= \frac{1}{2}e^{x^2} + C. \end{align*}
