sin 2x = cos x ; 0 < x < 360. Jawab : 2. cos 3x + cos (x+) = 0 ; 0 < x < Jawab : 3. Tan 2x + Tan (x - 30) = 0 : -90< x< 90. Jawab : b. Menggunakan rumus : sinx + cosx = 1 ; tanx + 1 = secx ; cotx + 1 = cosecx . cos 2x = 2 cos -1 = 1 - 2 sinx. sin 2x = 2 sinx cosx. sehingga soal menjadi bentuk persamaan kuadrat atau bentuk pemfaktoran. Contoh :
sqrt 3 sin x cos x
