himpunan penyelesaian dari 2 sin x=−√(3) untuk 0

2 sin x = -√3
Sin x = -1/2 √3 .................
1) dikuadran 3 : sin x = sin 240° => x = 240°
2) dikuadran 4 : sin x = sin 300° => x = 300°
HP = {240°, 300°}

2sinx = -√3
sinx = -½√3
sinx = -sin60

x = -60 + k . 360
k = 0 → x = -60
k = 1 → x = 300
k = 2 → x = 660 (TM)

x = (180 - (-60)) + k . 360
x = 240 + k . 360
k = 0 → x = 240
k = 1 → x = 600 (TM)

HP = {-60, 240, 300}
