| Topic | Trig Graphs & Exact Values |
| Type | Read parameters from graph of transformed trig function |
| Difficulty | Easy -1.3 This is a straightforward question testing basic understanding of sine function transformations. Part (i) requires reading amplitude and period from a graph (standard pattern recognition), while part (ii) involves sketching a simple vertical translation of sin x. Both parts are routine exercises with no problem-solving or multi-step reasoning required, making this easier than average. |
