minus-squareltxrtquqlinkfedilinkEnglisharrow-up2·4 hours ago A straight line in polar coordinates with the same tangent would be a circle. I’m not sure that’s true. In non-euclidean geometry it might be, but aren’t polar coordinates just an alternative way of expressing cartesian? Looking at a libre textbook, it seems to be showing that a tangent line in polar coordinates is still a straight line, not a circle.
