TOLONG BANTU DENGAN CARA KERJA YA.
penting banget besok dikumpul sebelum 07.15
tentukanlah nilai perbandingan trigonometri yang lain jika diketahui sudut lancipnya :
a. tan α =
b. sin β =
c. cotan α = 2

Answer 1

A) sisi miring segi tiga = 5
Sin A = 3/5 , Cosec A = 5/3
Cotg A = 4/3
CosA= 4/5 , Sec A = 5/4
B) sisi pengapit segi tiga = 5
Cos B= 5/13, Sec B = 13/5
Tg B= 12/5= 2,4 , Cotg B = 5/12, Cosec B = 13/12
C) Sisi miring segitiga = akar 5
Sin A = 1/5 x akar 5, Cosec A = akar 5
Cos A = 2/5 x akar 5, Sec A = (akar 5) / 2
Tg A = 1/2

Answer 2

A) sisi miring segitiga = 5
Sin A = 3/5 ,
Cosec A = 5/3
Cotg A = 4/3
Cos A= 4/5 ,
Sec A = 5/4

B) sisi pengapit segitiga = 5
Cos B= 5/13,
Sec B = 13/5
Tg B= 12/5= 2,4 ,
Cotg B = 5/12,
Cosec B = 13/12

C) Sisi miring segitiga = √5
Sin A = 1/5 x √5,
Cosec A = √5
Cos A = 2/5 x √5,
Sec A = (√5) / 2
Tg A = 1/2
