Replace the polar equations in Exercises 23-48 by equivalent Cartesian equations. Then describe or identify the graph.

40.

I think I have it solved, but I'm unsure whether I am correct or not.. All problems in this section have an [LaTeX ERROR: Compile failed] to convert to Cartesian (ie [LaTeX ERROR: Compile failed] ). However, this problem does not.

So I multiplied the entire problem by [LaTeX ERROR: Compile failed] which gave me the following:

[LaTeX ERROR: Compile failed]

[LaTeX ERROR: Compile failed]

[LaTeX ERROR: Compile failed]

[LaTeX ERROR: Compile failed]

[LaTeX ERROR: Compile failed]

Is this correct? Can I drop the [LaTeX ERROR: Compile failed] sign? And if so, why?

Thanks!
