Perbandingan Trigonometri
Perbandingan trigonometri pada segitiga siku-siku yang
paling utama ada 3 yaitu sinus (disingkat sin), cosinus
(disingkat cos) dan tangen (disingkat tan).
Untuk bisa menentukan perbandingan trigonometri suatu
segitiga siku-siku, terlebih dahulu kita harus bisa
menentukan mana sisi miring, sisi depan dan sisi samping
suatu sudut pada segitiga siku-siku.
