Berapa integral dari 1. Sin 3x 2. Sin kuadrat x 3. 2 sin 4x cos 2x 4. (sin 5x sin 4x) Cept d jawab yaaa lagi butuh

1.[tex]\int sin(3x) dx = -\frac{1}{3} cos(3x)+C[/tex]
2.[tex]\int sin^2(x) dx = -\frac{1}{2}\int cos(2x)dx= -\frac{1}{4}sin(2x) + C[/tex]
3.[tex]\int sin(6x)dx + \int sin(2x)dx= -\frac{1}{6}cos(6x) - \frac{1}{2}cos(2x)+C[/tex]
4.[tex]-\frac{1}{2}(\int cos(9x)dx - \int cos(x) dx )= -\frac{1}{2}(\frac{1}{9}sin( 9x)-sin(x)) + C[/tex]
