Transform the given polar equation to rectangular coordinates, and identify the curve represented. $$r=\frac{5}{3\sin\theta-4\cos\theta}$$ Any tips? The first thing I tried was replace $\sin\theta$ and $\cos\theta$ with $y/r$ and $x/r$ respectively. Then what do I do? Thanks!

Hint: $$3r\sin \theta - 4r\cos\theta=5$$

  • $\begingroup$ I did it, but one more question (now im doing anohther problem) if I get rcos^2teta is that the same as x^2? $\endgroup$

  • $\begingroup$ Perhaps you should ask that as a separate question. $\endgroup$
