It has been resolved, and I figured out precisely where I was wrong. My understanding of an ellipse was derived from the parametric representation of a circle, where x = acos(t) and y = bsin(t). In other words I just imagined taking a circle and stretching it in one dimension or another. This...

That makes a kind of sense in its own right, and I can easily derive the official equation for r from that. However, intuitively I am still at a loss. What exactly did I create, if not an equation for finding the length r, given any angle? Perhaps this will make more sense after I practice some...

Okay, so I have just broken into the polar coordinate system, and I like to derive things on my own to strengthen my intuition. I decided to try and derive the equation of an ellipse swiftly on my own, and had the high ambitions of eventually deriving the area of an ellipse with polar...

Citan Uzuki, thank you very much. Order has been restored. I am quite a fool.

That makes perfect sense, and I am still perplexed. I suppose the graph is what I have an issue with. In my mind I expect it to show equivalent exchange at all points, and it does not. It actually shows the inverse. This is what happens when I do not get enough sleep it seems.

My Fundamental Math Failing This should illicit a chuckle or perhaps despair in humanity. The statement "One silver piece is equivalent to two copper pieces" is not equivalent to the equation "S = 2C" (Where S = silver and C = copper). I cannot for the life of me figure out why. I can work...

Hmm, so its hard imaging that a 1kg weight will slow down as fast as a 100kg weight when sliding across the same surface in real life. Yeah, I can see why that wouldn't make sense intuitively. Perhaps it would help to consider how external forces influence these. It would take 100x as much force...

Okay, so I am somewhat new to physics (finishing up my first Mechanics/EM course), and I often get stuck on concepts until they make sense to me intuitively. Everything to do with translational motion made sense instantaneously, and I have powered through EM, but I have always struggled with...
