I have an integral `inte1` as below: f[x_] := PDF[NormalDistribution[0, 1], x]; F[x_] := CDF[NormalDistribution[0, 1], x]; inte1 = Integrate[f[x]*x^2, {x, -∞, k}] // FullSimplify which is: [![enter image description here][1]][1] But I want to show it in terms of `F[x]`: [![enter image description here][2]][2] How can I achieve this? Many thanks! [1]: https://i.sstatic.net/bUwlom.png [2]: https://i.sstatic.net/zRWrTm.png
