Thank you. I see why it sounds like I am just asking for answers. Conjugate diameters of an ellipse are two lines: One that is parallel to a tangent line and goes through the center, and another that goes through both the center and the point the tangent line passes through. I have been putting a lot of thought into this, and have not come up with very much. At this point, I think I made some progress though. An ellipse is really just a stretched circle, right? So if a circle is \((r\cos(t),r\sin(t))\) an ellipse is the same, but stretched- meaning instead of both the x and y having r, they have different constants? This means that if conjugate diameters in a circle are \(\frac{\pi}{2}\) apart from each other in a circle, the same is true in an ellipse (meaning you can add \(\frac{\pi}{2}\) to t)?
