Tentukan perbandingan trigonometri sudut lancipnya,jika mungkin sederhanakan!
a) cos 960°
b) cot 3750°
c) sec 1140°

kekkaiisshi Cos 960
= cos(2. 360 + 240)
= cos 240
= cos(180 + 60)
= -cos 60
= -1/2

cot 3750
= cot(10. 360 + 150)
= cot 150
= cot(180 - 30)
= -cot 30
= -√3

sec 1140
= cari sendiri,,,, :v
