Contoh Soal Grafik Fungsi Trigonometri Berserta Jawabannya

1. Persamaan grafik fungsi pada gambar adalah : Jawab : x = 150 → y= -sin 2 (x −15)0 = -sin 00 = 0 �benar x = 1050 → y= -sin 2 (x −15)0 = - sin 1800 = - sin(1800 - α ) →α = 00 maka - sin 1800 = -sin 00 = 0 �benar Nilai minimum y= -1 yaitu di x = 600 x = 600 → y= -sin 2 (x −15)0 = - sin 900 = - 1 �benar Nilai maximum y= 1 yaitu di x = 1500 x = 1500 → y= -sin 2 (x −15)0 = - sin 2700 = - sin(1800 +α )= sin α = 1 �benar
