Higher June 2018 Paper 1 Q18
18 Here is the graph of \(y = \sin x^\circ\) for \(-180 \leqslant x \leqslant 180\)
On the grid, sketch the graph of \(y = \sin x^\circ - 2\) for \(-180 \leqslant x \leqslant 180\) (2)
| Answer | Mark | Mark scheme |
|---|---|---|
| Graph drawn | C2 | for graph translated by \(-2\) in the \(y\) direction |
| (C1 | for a graph translated in the \(y\) direction OR for a correct graph through four of the five key points) |
Additional guidance
Key points: \((-180, -2)\), \((-90, -3)\), \((0, -2)\), \((90, -1)\), \((180, -2)\)
