Trigonometri
Perbandingan trigonometri adalah perbandingan ukuran, sisi-sisi suatu segitiga siku siku apabila ditinjau dari salah satu sudut yang terdapat pada segitiga tersebut.
•Rumus Trigonometri :
∆ABC ~ ∆ADE ~ ∆AFG ~ ∆AHI
BC/AC = DE/AE = FG/AG = HI/AI = SIN A
AB/AC = AD/AE = AF/AG = AH/AI = COS A
BC/AB = DE/AD = GF/AF = HI/AH = TAN A
•Rumus Perbandingan :
Sin A = de/mi =bc/ac = a/b
Cos A = sa/mi = ab/ac = c/b
Tan A = de/sa = bc/ab = a/c
Sec A = 1/cos A = ac/ab = b/a
Cosec A = CSC A = 1/sin A = ac/bc =b/a
Cotan A = Cot A = ctg A = 1/Tan A = ab/bc = ca
