Penjelasan dengan langkah-langkah:
TriGonomeTri
Menyatakan perbandingan trigonometri dalam perbandingan trigonometri sudut pelurus.
a) Sin 140°
Sin (180-40) = Sin 40°
b) Cos 138°
Cos (180-52) = Cos 52°
c) Tan 159°
Tan (180-21) = Tan 21°
d) Cot 97°
Cot (180-83) = Cot 83°
e) sec 108°
sec ( 180 - 72) = sec 72°
f) Cosec 165°
Cosec ( 180 - 15) = Cosec 15°
