Convert polar equation of a circle to rectangular equation

The video tutorial discusses solving a mathematical problem involving trigonometric functions and equations. The teacher explains why certain methods, like multiplying by sine, are not ideal due to complications with sine squared terms. Instead, the teacher demonstrates multiplying by R to simplify the equation, leading to a form that can be solved by completing the square. This process reveals the equation of a circle with a specific radius and center. The tutorial concludes with a visualization of the solution and a recap of the key steps involved.

Explain the final equation derived from the process discussed.
