| Topic | Curve Sketching |
| Type | Two stretches from same function |
| Difficulty | Easy -1.8 This is a routine sketching exercise requiring only basic recall of sine transformations (horizontal stretch by factor 1/2 and vertical stretch by factor 2). No calculations, problem-solving, or conceptual insight needed—just standard graph sketching from memory of transformation rules. |

---8 Draw two sketches of the graph of $y = \sin x$ in the range $0 ^ { \circ } \leq x \leq 360 ^ { \circ }$.\\
(i) On the first sketch, draw also a sketch of $y = \sin ( 2 x )$.\\
(ii) On the second sketch, draw also a sketch of $y = 2 \sin x$.
