Step 1
In polar coordinates, we use $r$ and $\theta$ to represent a point $(x, y)$. The conversion formulas are: $x = r \cos \theta$ $y = r \sin \theta$ Step 2: Substitute the conversion formulas into the given rectangular equation. The given rectangular equation is $6x Show more…

Equation of a line in polar form: $$r=\frac{C}{A \cos \theta+B \sin \theta}$$ For the line $A x+B y=C$ in the $x y$ -plane with slope $m=-\frac{A}{B}$ and $y$ -intercept $\left(0, \frac{C}{B}\right),$ the corresponding equation in the $r \theta$ -plane is given by the formula shown. (a) Given the line $2 x+3 y=12$ in the $x y$ -plane, find the corresponding polar equation and (b) verify that $-\frac{A}{B}=-\frac{r(\pi / 2)}{r(0)}$.
