Answer:

Step-by-step explanation:
The given cylindrical equation is

Multiply both sides by r.
 .... (1)
           .... (1)
The required formulas are

Substitute  in equation (1).
 in equation (1).


Add 1 on both sides.

 
                    ![[\because (a-b)^2=a^2-2ab+b^2]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%28a-b%29%5E2%3Da%5E2-2ab%2Bb%5E2%5D)
It is the equation of a circle centered at (0,1) with radius 1.
Therefore, the equation in rectangular coordinates is  .
