Galladeaviero2 Sin x = 1 Sin x = 1/2 (kuadran I dan II) Sin x = Sin 30° x = 30° + k . 360° k = 0 => x1 = 30° + 0 . 360° = 30° => x2 = (180° - 30°) + 0 . 360° = 150° Jadi, HP {30° , 150°}

2 sin x=1 sin x= 1/2 sin x= sin 30 x= 30 + k. 360
k=0=> 30(v) k=1=> 30+360 = 330(x)
x= (180-30) +k. 360 x= 150+k.360 k=0=> 150(v) jadi hp nya {30,150}
Sin x = 1/2 (kuadran I dan II)
Sin x = Sin 30°
x = 30° + k . 360°
k = 0 => x1 = 30° + 0 . 360° = 30°
=> x2 = (180° - 30°) + 0 . 360° = 150°
Jadi, HP {30° , 150°}
sin x= 1/2
sin x= sin 30
x= 30 + k. 360
k=0=> 30(v)
k=1=> 30+360 = 330(x)
x= (180-30) +k. 360
x= 150+k.360
k=0=> 150(v)
jadi hp nya {30,150}
