 Sci Advisor HW Helper P: 4,300 Yep, if you use a logarithmic axis then suddenly exponential functions are drawn as straight lines, and when you have a polar curve $r(\theta)$ you can plot it in polar coordinates ($x = r \cos\theta, y = r \sin\theta$) or you can plot r vs. $\theta$ ($x = r, y = r(\theta)$) and it looks completely different. This is why mathematics usually tries to describe the functions in another way (e.g. as the solution of some equation, or by certain properties) rather than just giving it as a graph. Note that some branches of mathematics - especially those like linear algebra and differential geometry, which are heavily influenced by physics - make quite a point out of writing things in a coordinate free way.
