9.
(a) Sketch the curve \(y = \sin x\), for values of \(x\) in the range \(x = 0^\circ\) to \(x = 360^\circ\) . [1]
(b) Sketch the curve \(y = \tan x\), for values of \(x\) in the range \(x = 0^\circ\) to \(x = 360^\circ\) . [1]
| Scheme | Marks | Comments |
|---|---|---|
 | C1 | Clear intention to draw a curve. Curve must pass through (0,0), (180,0) and (360,0). AND intention to have maximum at (90,1) and minimum at (270,-1). Ignore curve shown for values x < 0° or x > 360°. |

 | C1 | Clear intention to draw a curve with positive gradient. Curve must pass through (0,0), (180,0) and (360,0). AND have inflection point at (180,0). There must be an intention not to cross the asymptotes at x = 90°, x = 270°. Ignore curve shown for values x < 0° or x > 360°. |
