To convert an equation given in polar form (in the variables

You have to remember that your equation may need some algebraic/trigonometric manipulations before being transformed into rectangular form; for example, consider:

Now you use the above transformations, and get:

Which is the equation of a straight line!

A more complicated situation can be the following example:

You can write:

Take the tangent of both sides and multiply and divide by

Transforming you get:
