r=2sin0-3cos0

explainusing the formula that links Cartesian to Polar coordinates.∙y=rsinθ∙x=rcosθthen : rsinθ=3rcosθ+2and rsinθ−3rcosθ=2hence r(sinθ−3cosθ)=2

⇒r=2sinθ−3cosθ

r = 2/(sinθ−3cosθ)

Explanation:y = r sin θ
x = r cos θThen: r sin θ=3r cos θ + 2and r sin θ −3r cos θ = 2thus r (sin θ−3 cos θ) =2

⇒r =2/(sin θ−3 cos θ)
