9. Polar Equations / Convert Equations Between Polar and Rectangular Forms / Problem 1

Problem 1

Convert the given rectangular equation to a polar equation that expresses $r$ in terms of $θ$ .
$y=8$

$r=\frac{8}{\sin\theta}$

$r=8\sin\theta$

$r=\frac{\sin\theta}{8}$

$r=\frac{8}{\cos\theta}$

Convert the given rectangular equation to a polar equation that expresses rrr in terms of θθθ .y=8y=8y=8
