    My whole point is that a “straight done”, in general, doesn’t exist in the first place. Because in general definitions are actually really hard.

    It’s not that it’s important to me. It’s that I’ve spent many parts of my day on the phone with the bank, and never should be taken for more than an asshole on the internet. Sorry if you thought I was more invested than that.

    Except here you said here

    That they all must be equal.

    Tangents all be equal to the point would be exponential I thinks. So I assume you mean they must all be equal.

    Granted I assumed constant, because that’s what actually produces a “straight” line. If it’s not, then cos/sin also fall out as “straight line”.

    So I’ve either stretched your definition of straight line to include a circle, or we’re stretching “straight line”

    But then your definition of a straight line produces two different shapes.

    Starting with the same definition of straight for both. Y(x) such that y’(x) = C produces a function of cx+b.

    This produces a line

    However if we have the radius r as a function of a (sorry I’m on my phone and don’t have a Greek keyboard).

    R(a) such that r’(a)=C produces ra +d

    However that produces a circle, not a line.

    So your definition of straight isn’t true in general.
