hp dari...... a. sin 6x+sin 2x-sin 4x=0, b. sin 5x-sinx-cos 3x=0 c. cos 6x -cos 2x=0 d. cos 5x+cos 3x-cos 4x=0 e. sin 3x+sin x=√2 sin 2x

a. [tex]x = \frac{\pi n}{2}, n \in Z[/tex]
[tex]x = \frac{\pi n}{2}-\frac{\pi}{4}, n \in Z[/tex]
[tex]x = \pi n-\frac{\pi}{6}, n \in Z[/tex]
[tex]x = \pi n+\frac{\pi}{6}, n \in Z[/tex]

yg lain bisa mungkin bisa menambahkan
