| Topic | Curve Sketching |
| Type | Identify transformation from two graphs |
| Difficulty | Moderate -0.8 This is a straightforward C2 transformation question requiring students to identify simple transformations of y = sin x from graphs. Students need only recognize basic transformations (likely vertical/horizontal shifts or stretches) and write the transformed equations - a routine exercise testing recall of transformation rules with minimal problem-solving required. |

Question 9:
(i) [y = ] $2\sin x$ oe | 1
[1]
(ii) [y = ] $\sin (0.5x)$ oe | 2
[2] | M1 for [y = ] $\sin (2x)$9 Figs. 5.1 and 5.2 show the graph of $y = \sin x$ for values of $x$ from $0 ^ { \circ }$ to $360 ^ { \circ }$ and two transformations of this graph. State the equation of each graph after it has been transformed.\\
