  • Oddly enough, on a computer, I have not seen secant, cosecant, or cotangent.

    I have seen sin, cos, tan, arcsin, arccos, and arctan.

    Though the arc functions will only have one parameter, so if this is homework, you’ll probably be avoiding the arcs and using secant and friends

    Anyways:

    sin ( angle )

    Term In this example
    Parameter Angle is the parameter. It’s in radians, so in Java you’ll use a conversion like Math.toRadians(a) on whatever number you’re going to use as an argument
    Argument If I were to call sin(Math.PI / 4) then I would be passing the argument π / 4 to the function.
    In other words, if a parameter is a question, then an argument is an answer. If a parameter is a coin slot, than an argument is the coin you choose to insert.
    Operation An operation is practically synonymous with “function”. It is performed on inputs to arrive at an output. However, usually in code, I hear “operation” used to describe things like /, *, and +. Things that have multiple inputs and a single output, all of the same form.

    If someone is asking you, "which operation should you use in the body of function sin ( hyponetuse, opposite ) then I imagine the expected answer would be, / because

    1. / is an operation, and because
    2. opposite / hypotenuse will perform the division that yields the sine of whatever triangle those two sides belong to.

  • An algorithm is the meat of a function. It’s the “how.”

    And if you’re using someone else’s function, you won’t touch the “how” because you’ll be interacting with the “what.” (You use a function for what it does.)

    You will be creating your own algorithm by writing code, however. Because an algorithm is just a sequence of steps that, taken together, constitute an attempt at achieving an objective.

    Haus is saying all the little steps that go into approximating sine occur directly on the hardware.














  • I can take a guess at what it tells us.

    We’re lonely. We get no physical contact. No touch. No warmth. And it’s not really socially acceptable for us to seek those things, because men are scolded for emotions and vulnerability. We are scolded for anything that would enable intimacy.

    And it’s to such an extent that most men are so repressed they don’t even realize they crave intimacy. They don’t even have the vocabulary to describe their need for intimacy.

    Now introduce, to such a man, a “sister.”

    Heavy emphasis on the quotes.

    The “story” of the porn, using their family ties as a shortcut, quickly establishes that she lives with him. She bonds with him. It’s socially acceptable for him to hug her, to wrestle with her, maybe even to cuddle her. And she will always be there, because her connection to him runs deeper than most “romantic” relationships can (we’re still assuming this man can’t articulate his own need for intimacy), so he doesn’t need to worry about her abandoning him.

    Naturally, this emotionally repressed man is going to look at this fictional family member, this figment of his suspension of disbelief, and say, “well I want to 🦆 her!” (I always find my keyboard’s lack of profanity amusing. I refuse to teach such an innocent piece of software how to cuss.)

    What he really means is that he appreciates that intimacy. And cannot really get turned on in its absence. But he can’t say that. He can’t admit that or even know that. Because this man is not only starved of all of the above: he can’t even articulate this starvation.

    Daughters? Sisters? Mothers? They all serve the same purpose as a shortcut – “here’s a person who is intimate and trusting with you by default.” The familial bond is a fast, easy way to establish prebuilt trust and affection without spending 20-30 minutes on storytelling or 20-30 hours of therapy trying to convince a repressed audience that it’s okay to have a deep, intimate, trusting connection with this consenting woman.

    In other words, what it tells us about society isn’t good.


  • It sounds like you were distressed and left because you didn’t know what to do or how to help.

    That’s empathy. Feeling uncomfortable when you see people in pain is empathy. And it’s normal. It’s normal for you to feel distressed around her as you hear her account. It’s normal to want to leave. It’s normal to feel guilty about leaving. It’s normal to wonder if you could have done more to help catch the bastard.

    This is awful. What you just saw is awful. What you just experienced is legitimately uncomfortable.

    And it’s hard for people to wrap their heads around, because how could your pain be valid when it’s a response to seeing someone in “real” pain? How could your pain be important when it’s nothing more than the faint echo of the pain you’re witnessing someone else go through?

    But it hurts. As selfish as it feels to hurt at a time like this, it still hurts.
