Kordinat kutub (2,2)

cari jari jari
=√x² + y²
=√2² + 2²
=√8
= 2√2

cari sudut
tan alpha = y/x
tan alpha = 2/2
tan alpha = 1
alpha = 45°

koordinat kutub (2√2 , 45°)

#La

x = 2
y = 2

r = akar [2^2 + 2^2]
= akar [4 + 4]
= akar 8
= akar [4 × 2]
= 2 akar 2
tan a = y/x
tan a = 2/2
tan a = 1
a = arc tan 1
a = 45°
koordinat kutub = (r , a) = (2 akar 2 , 45°)
Jadi koordinat kutubnya adalah (2 akar 2 , 45°)
