koordinat kartesius dari titik P(6, 3000 derajat ) adalah ..

r = 6

Tetha = 3000°

x = r cos tetha

= 6 cos 3000°

= 6 cos( 8. 360 + 120)

= 6 cos (120)

= 6 cos (180 -60)

= 6 (-1/2)

= - 3
y = r sin 3000

= 6 sin(360*8 + 120)

= 6 sin (120)

=6 sin(180-60)

= 6 sin(60)

= 6 (1/2 akar 3)

= 3 akar 3

(x,y) = (3akr 3 , -3)
