Cambridge IGCSE Mathematics 0580 syllabus for exams in 2028, 2029 and 20302028–2030

Practise sketching sine and cosine graphs over 0° to 360° and solving trigonometric equations with all valid angles in range.

How this is tested

solve trig equations over 0° to 360°, giving both valid angles when required
use quadrant facts to handle reflex angles and angle pairs with matching sine or cosine values

[Maximum number: 2]

Sketch the graph of $y=\cos x$ for $0^\circ\leqslant x\leqslant360^\circ$ .
