comment Understanding the proof for: $d(f^*\omega)\overset{!}{=}f^*(d\omega)$
I see, but where does the $\phi$ in $\sum_{i,j}\frac{\partial f}{\partial y_i}\circ\phi(\frac{\partial (\phi_i)}{\partial x_j}dx_j)$ come from?

@EhsanM.Kermani I see it now. $0\wedge\omega=0\cdot\omega=0$. I fogot about that.
