soal liat di gambar. btw ada yg bisa bantu? aku ga paham.
Jawab:
trigonometri
segitiga siku
d= sisi depan
s = sisi samping
m = sisi miring
gambar (a)
untuk sudut α ,
d = b
s= a
m = c
perbandingan trigonometri
sin α = d/m = b/c
cos α = s/m = a/c
tan α = d/s = b/a
cosec α = 1/sin α = c/b
sec α = 1/cos α = c/a
cot α = 1/tan a = a/b
gambar 2
untuk sudut α,
d = p
s = q
m = r
perbandingan trigonometri
sin α = d/m = p/r
cos α = s/m = q/r
tan α = d/s = p/q
cosec α = 1/sin α = r/p
sec α = 1/cos α = r/q
cot α = 1/tan a = q/p
