Question: User: Explain how to solve this in malayPERCUBAAN NEGERI SABAH (SET 1) 2023 (NO 11) 11) Rajah 11 menunjukkan ketinggian air laut ketika pasang surut. Diagram 11 shows the height of an ocean tide. h (m) 3 6 Parsa air Water level 0 -3 -6 t (jam) t (hour) Rajah 11 Diagram 11 Antara berikut, yang manakah fungsi trigonometri yang mewakili ketinggian pasang surut air itu? Which of the following trigonometric function that represents the height of the tide? A) 12 sin 6t B) 12 cos 6t C) 6 sin 30t D) 6 cos 30t Graph shape/position hint: center, sinusoidal curve starting at (0,0), rising to a maximum near (3,6), crossing again near (6,0), falling to a minimum near (9,-6), and returning to (12,0). PERCUBAAN NEGERI SABAH (SEMPORNA) 2023 (NO 27) 12) Graf manakah yang mewakili y = kos x° bagi 0° ≤ x ≤ 360°? Which graph represent y = cos x bagi 0° ≤ x ≤ 360°? A) B) Graph shape/position hint: bottom-left, cosine graph options are shown; B appears to show a curve starting near y = 1 at x = 0 and peaking near the top dashed line.
