Penjelasan dengan langkah-langkah:
gunakan rumus :
sinx = 1/cosecx
sin3x = 1/cosec30° untuk : -100° ≤ x ≤ 100°
sin3x = sin30°
3x = 30° + k.360°
x = 10° + k 120°
k = 0
x = 10° + 0
x = 10°
k = 1
x = 10° + 120
x = 130° (tidak memenuhi interval)
k = -1
x = 10° - 120°
x = -110° (tidak memenuhi interval)
HP = { 10° }
