  Is this genuine? Like is the unit circle really fucking you up that bad?

  I’m pretty dumb, so I don’t understand this one.

    Probably that trigonometry is the highest math the average person will take?

      I got to calculus 2 and proceeded to forget everything through algebra II once I took a break from math for a semester.

  You leave my unit circle alone!

      Please elaborate.

  Believe this was featured in a paper that recently used trig to prove the Pythagorean theorem (previously thought to be a circular definition). I think some highschoolers cracked it as part of a mathematics challenge or something.

  Took me a minute to notice, but it was worth it

    Notice what??

    You can use the spoiler tag

    Notice what, exactly. I still don’t get it.

    • humblebun@sh.itjust.works ⁨3⁩ ⁨weeks⁩ ago

      Take a look again, it’s still there

  Why is it 1

  source

  • F04118F@feddit.nl ⁨3⁩ ⁨weeks⁩ ago

    It was freely chosen for simplicity.

    If you choose another R, the other sides (x and y) become Rcos(th) and Rsin(th)

    I don’t understand what is harmful about the unity circle either.

  • Wolf314159@startrek.website ⁨3⁩ ⁨weeks⁩ ago

    Because it’s a unit circle.

    for the same reason that rulers start with 1, it would be utterly pointless to use anything else.

    source

    • ryannathans@aussie.zone ⁨3⁩ ⁨weeks⁩ ago

      Your ruler starts with 1? How do you measure stuff between 0 and 1?

    SOH CAH TOA is just a trick to make rote memorization of procedure easier. Understanding the unit circle will let you understand what trigonometry is actually doing.

    Yeah, dividing a circle into 360 parts, then subdividing those by 60, and further subdividing those by 60 makes so much more sense than just using ratio of a number fundamental to circles themselves.

  the unit circle lives in my nightmares.
