1.1. The diagram shows the graph of $y=f(t)$, where $f(t)=cost,0^{\circ}\leqx\leq360^{\circ}.$

(i) Write down the maximum value of $y$ when $y=-2f(3t).$

(ii) Write down the value of $t$ for which this maximum occurs.

1.2. Find, in terms of $f(t)$, the combination of transformations that would map the graph of $y=f(t)$ onto the graph of $y=2-4sint,0^{\circ}\leqx\leq180^{\circ}.$
