Is this genuine? Like is the unit circle really fucking you up that bad?
You leave my unit circle alone!
I’m pretty dumb, so I don’t understand this one.
Pythagorean theorem.
Although, don’t solve this or else Pythagoras might throw you off of a boat
Pretty sure this is Pythagorean Identity, theorem is a²+b²=c²
Why?
SOH CAH TOA
Ah, sohcahtoa. Not to be confused with
Please elaborate.
Sine of theta is the ratio of the lengths of the Opposite side over the Hypotenuse (SOH). Cosine of theta is Adjacent over Hypotenuse (CAH). Tangent of theta is Opposite over Adjacent (TOA).
Oh you’re saying opposite site and adjacent site in English
Anyway how is the r=1 circle harmful for that?
the unit circle lives in my nightmares.
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.
Someone needs to turn this into loss
I’m fine doing SOH CAH TOA, but the unit circle can go fuck itself. Same with radians.
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.
Why is it 1
for the same reason that rulers start with 1, it would be utterly pointless to use anything else.
Your ruler starts with 1? How do you measure stuff between 0 and 1?
those are unlabeled, have you ever seen a ruler?
Zero is not unlabelled lol
It was freely chosen for simplicity.
If you choose another R, the other sides (x and y) become R*cos(th) and R*sin(th)
I don’t understand what is harmful about the unity circle either.
Any circle could have its radius technically be 1, as long as you set the units of measurement so that 1 equals the radius of the circle.
Because it’s a unit circle.
Took me a minute to notice, but it was worth it
Notice what, exactly. I still don’t get it.
Take a look again, it’s still there
I only see the double arrows.
When you look at it for a minute, your phone will dim the screen and in reflection you’ll see the person who has harmed you.
I’ve seen it! The bastard!
Notice what??
