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!

Why?

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??

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

Take a look again, it’s still there

Why is it 1

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.

Because it’s a unit circle.
Swedneck@discuss.tchncs.de 3 days ago
for the same reason that rulers start with 1, it would be utterly pointless to use anything else.
ryannathans@aussie.zone 3 days 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.

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