\includegraphics[max width=\textwidth, alt={}, center]{cacac880-5b44-4fae-8ed8-88a095db69cd-03_606_1515_260_274} The diagram shows two curves. One curve has equation \(y = \sin x\) and the other curve has equation \(y = f ( x )\).

1. In order to transform the curve \(y = \sin x\) to the curve \(y = f ( x )\), the curve \(y = \sin x\) is first reflected in the \(x\)-axis. Describe fully a sequence of two further transformations which are required.
2. Find \(\mathrm { f } ( x )\) in terms of \(\sin x\).
