Diketahui sin alfa 2/3 dan alfa disudut lancip.carilah nilai perbandingan trigonometri yang lain

sin alfa = 2/3

DE = 2
MI = 3

SA^2 = 3^2 - 2^2 = 9-4 = 5
SA = akar5

cos alfa = SA/MI = akar5/3 = 1/3 akar5
tan alfa = DE/SA = 2/akar5 = 2/5 akar5
cosec alfa = 1/sin alfa = 3/2
sec alfa = 1/cos alfa = 3/akar5 = 3/5 akar5
cot alfa = 1/tan alfa = akar5 / 2 = 1/2 akar5
