You leave my unit circle alone!
the unit circle lives in my nightmares.
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
Someone needs to turn this into loss
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).
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, exactly. I still don’t get it.
Notice what??
You can use the spoiler tag
No spoiler
Why is it 1
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.
