Question

Kuis ⁽⁹⁷⁾
Ubah ke koordinat polar
(√3, 1)

Answer 1

Jawaban:

(r,@) = (2,30°)

Penjelasan dengan langkah-langkah:

x=√3

y=1

polar = (r,@)

r=√(x²+y²)

r=√((√3)²+1²)

r=√4

r=2

tan@ = y/x

tan@ = 1/√3

maka @ = 30°

sehingga koordinat polar

= (2,30°)

Answer 2

Verified answer

Konversi

Koordinat Kartesius → Koordinat Polar

(x,y) → (k,a)

titik (√3 , 1)

kuadran I

k = √(x² + y²)

k = √((√3)² + 1)

k = 2

a = arc tan (y/x)

a = arc tan (1/√3)

a = 30°

Koordinat polar dr (√3 , 1) → (2 , 30°)
