The formula for graphing an Archimedean spiral is always given in polar coordinates. I need to know the formula in Cartesian coordinates (x,y). Can anyone help? Thanks.

It's an implicit equation that you can't solve for y.
So if , then by conversion to rectangular coordinates, we have
We can't simplify this any further...

Reason: used wrong spiral equation... ><
