Of course sine can appear in the solution for dynamical systems but the function itself is not dynamical. When evaluating sin(x) you do not need to know about the previous state.

We can’t conclude a dynamic approximation is a bad approach based purely on the fact the underlying function isn’t dynamic.
The function might nevertheless be easily approximated via dynamics — as in the case of predicting sine from seeing the recent history.
