Himpunan pentelesaian dari 2 sin x- tan x =0 ??

[tex]2 \sin(x) - \tan(x) = 0 \\ 2 \sin(x) - \frac{ \sin(x) }{ \cos(x) } = 0 \\ \frac{2 \sin(x) \cos(x) - \sin(x) }{ \ \cos(x) } = 0[/tex]
[tex] \sin(x) (2 \cos(x) - 1) = 0 \\ \sin(x) = 0 \\ atau \\ 2 \cos(x) = 1 \\ \cos(x) = \frac{1}{2} [/tex]
Jadi, nilai x yang memenuhi:
[tex] {0}^{0} , {60}^{0} ,{180}^{0} ,{300}^{0} , {360}^{0} [/tex]
