Ubah koordinat kutub menjadi koordinat cartesius A) a (6,30°) B) b (2,120°) C) c (8,45°)

A ( 6, 30)
( 6 cos 30, 6 sin 30)
= ( 6.1/2√3, 6.1/2)
= ( 3√3, 3 )
B ( 2, 120 )
= ( 2 cos 120, 2 sin 120 )
= ( 2.-1/2, 2.1/2√3)
= ( -1, √3 )
C ( 8, 45 )
= ( 8 cos 45, 8 sin 45)
= ( 8.1/2√2, 8.1/2√2)
= ( 4√2, 4√2)
