    Sinus sexual: f(x) = sin x

    Cubic sexual: f(x) = x³

    Hyperbole sexual: f(x) = 1/x

    Exponential sexual: 2^x

    Are we doing cutesy metaphor here or should I dedicate actual time to working out some best of fits here based on reported attraction and relative phenotype in given populations?

    I get that straight is a straight line, and “cosexual” is the cosine function, but can someone explain the joke for the other two?

      For y = x^2, both x and -x equal to the save value of y.

      For example: 2^2 = -2^2 = 4.

      For the y = sqrt(x), for every positive value of x, there is positive and negative value of y.

      For example: sqrt(4) = -2 = 2.

        erm actually (in the nerdiest voice possible) it’d be more accurate to say x² = y or y = ±sqrt(x) instead of y = sqrt(x) since the square root symbol only gives the principal root

        I guess I have no idea how the math symbols are supposed to relate to sexual orientation. Can you help with that part?

        Also, IIRC square root of 4 has only one answer: 2, but negative 2 squared is equal to 4. The functions are asymmetric that way? Is that incorrect? This is all from vague memories of high school and college math.

        Does the square root function always give a positive and negative answer? And we in society just kind of forgot about the negative one?

          The rule (meme) came to me in a dream. Dreams are weird, and i have no idea what it is supposed to mean. I just though its funny, and decided to post it.

            Fair enough. Thanks for sharing it! I just wish I was more math literate so I could understand it better.

          Does the square root function always give a positive and negative answer?

          Yes. But in real systems you can usually know what the sign will be from context.

          the joke only really works for straight being straight and gay being “not straight” but also everything is above the y axis.

          The bisexual one is funny because it doesn’t really make sense, it’s the “broken rule of three” - where the last one doesn’t match the first two, and then the fourth one is just a pun of sorts

          The square root function only has a single answer for every x. This is intentional. The technical definition of function means there can only be a single y value for every x value. Of course, there are situations where you need to consider the positive and negative square root, and that’s why the quadratic equation has the ± symbol.
