koordinat kutub titik A (√3,3) adalah

r^2 = (akar3)^2 + 3^2
r^2 = 3 + 9
r^2 = 12
r = akar12
r = 2 akar3

tan@ = y/x
tan@ = 3/akar3
tan@ = akar3
tan@ = tan60°
@ = 60°

jwb. (2akar3, 60°)

koordinat kutub
(√3, 3) → x positif dan y positif, di kuadran I

r = √(x² + y²)
r = √(√3² + 3²)
r = √(3 + 9)
r = √12
r = 2√3

tan α = y/x = 3/√3 = √3
α = 60°

(2√3, 60°)
