$$\int e^{6x}\cos7x \mathrm dx$$
I was trying integration by parts:
$$\int e^{6x}\cos7x \mathrm dx = \frac{1}{7}e^{6x}\sin(7x)-\frac{6}{7}\int e^{6x}\sin(7x)\mathrm dx$$
however I get an equally hard integral on the right.

I'd like to obtain a symbolic result for the following integral:
Sigmoid[x_] := 1/(1 + Exp[-x])
Integrate[Sigmoid[x]*Log[Sigmoid[x*w]], {x, -Infinity, Infinity}]
The correct answer is -Pi^2 (w^2 + 1)/(12w).
Mathematica can do it for explicit small integer values of $w$ (eg, w=1 or w=2).
