💡 Exam Tips for Trigonometric Graphs
- Learn the 5 key points for each wave (0°, 90°, 180°, 270°, 360°) — you can sketch from these alone
- Period vs amplitude: period is the horizontal width of one cycle; amplitude is the vertical height from the midline
- Multiple solutions: if asked to solve sin x = k or cos x = k in a range, always check for a second solution using symmetry
- tan at 90°: always show the asymptote — the tan graph does NOT cross x = 90°
- Transformation direction: sin(x + 30°) moves LEFT by 30° (inside bracket = opposite direction)
