X = r.cos α
x = 6.cos300
x = 6.cos60
x = 6. 1/2
x = 3
y = r.sin α
y = 6.sin300
y = 6.-sin60
y = 6. -1/2 √3
y = -3√3
A(3,-3√3)
SEMOGA MEMBANTU :)
•Pertanyaan :
Koordinat Cartesius dari titik (6,300°) adalah..?
----------------------------------------------
•Penyelesaian :
Diketahui :
titik (6,300°)=(r,teta)
r=6
teta=300°
Ditanya : Koordinat Cartesius..?
Koordinat Cartesius=(x,y)
x=r×Cos teta
x=6×Cos 300°
x=6×Cos (360°-60°)
x=6×Cos 60°
x=6×1/2
x=3
y=r×Sin teta
y=6×Sin 300°
y=6×Sin (360°-60°)
y=6×Sin-60°
y=6×(-1/2√3)
y=-6/2√3
y= -3√3
Koordinat Cartesius=(x,y)=(3,-3√3)
