  • Because if the majority of people following a particular religion reject a prior view as false or wrong, then arguably that view is no longer part of the religion.

    Religions aren’t crisp, unchanging, monolithic entities where everybody believes the same thing forever. If we’re talking about judaism in the sense of the views and practices jewish people actually subscribe to, then that seems like we are referring to beliefs they actually hold in a mainstream/current sense, not beliefs they previous held but now reject?


  • Operating System Concepts by Silberschatz, Galvin and Gagne is a classic OS textbook. Andrew Tanenbaum has some OS books too. I really liked his OS Design and Implementation book but I’m pretty sure that one is super outdated by now. I have not read his newer one but it is called Modern Operating Systems iirc.






  • It does if you claim to know cos (A) = 1.

    My issues with this are: Your solution did not originally claim this, it is not stated anywhere in the problem and it leads to exactly the same kind of foundational issues in the context of showing “algebraically” why cos(x)=1 at integer multiples of 2pi now.

    The question as given is illposed. You have to know something. If not, why not ask a philispohical question like what is trigonometry even?

    Agreed. It’s at least vague/misleading. This is apparently for a precalc clep exam, so the only real sane definition a student would know to fall back on here would be geometric definitions for sine and cosine. What I think the intent of the problem is, is to build intuition on knee jerk facts about sine/cosine rather than something particularly formal?



  • I realized in retrospect I misread the header so I apologize for that.

    I’m still betting they aren’t expecting a true algebraic or analytic solution here. Things like finding max/min points, finding arbitrary particular values of trig functions, solving trigonometric equations and so on can be notoriously hard in the absence of geometric reasoning/intuitions.

    Later on if you decide to study calculus you might eventually see the sine and cosine functions defined rigorously via infinite series. That may sound convoluted, but part of the purpose of doing that is because of the difficulties of the issues mentioned above. Basic sounding facts like: What is sin(0.1234)? are not so easy to answer where you are at but can be dealt with more conveniently using these kinds of tools from calculus.

    The questions being asked here are also just kind of typical knee jerk facts that most people want students coming out of a trig class to just know.

    I think your reasoning geometrically seems very on the right track. Appealing to the unit circle or the graph of y=sinx for these feels correct in the sense of what a trig student would be expected to know coming out of or during a trig course.




  • There’s nothing here that tells you that you need to use some technique from algebra explicitly as far as I can see?

    Edit: I misread. See my follow up comment too.

    The usual trig functions like sine and cosine are famous examples of transcendental functions so I very seriously doubt there is some clever algebra trick you’re missing that the author intends you to do.

    I’d assume your instructor (or the author) is expecting you to use your geometric knowledge about the unit circle on these if you haven’t covered inverse trig functions yet. But I also can’t really read their mind, so your best bet might be to just directly ask them?

    Edit: This could also depend on what trigonometric identities you know so far too.

    If you have a fixed collection of processes to run on a single processor and unlimited time to schedule them in, you can always brute force all permutations of the processes and then pick whichever permutation maximizes and/or minimizes whatever property you like. The problem with this approach is that it has awful time complexity.

    Edit: There’s probably other subtle issues that can arise, like I/O interrupts and other weird events fwiw.

    Have you studied philosophy of religion? Sounds a lot like you haven’t. Maybe reading up on it will help you? You can fix your reading comprehension and also learn not to say the dumbest shit possible on topics of religion. It’s really a win-win for you.
