The anime seems off somehow.
hmm what next
Let the length of AB be 1. Then use the Law of Sines and/or the Law of Cosines to find the length of AD, and other relevent lengths and angles. Refer to the figure in >>389233
. (Note that this is somewhat cheating because it uses trig, but figuring out how to solve it with just elementary geometry is really fucking hard
I don't want to sin.
Well then cos instead.
I believe I forgot how to do that.
Or maybe I never learned.
Those are some powerful tools.
But I'm trying to learn something different right now and I want to better understand a magical formula if I am to use it.
Fast is good, right?
I mean… none of us have all the time in the world.
It's been a long time since I did geometry, but the angles of a triangle always add up to 180, right? Shouldn't be that hard
Yeah, no, I'm too far out of practice, I can't figure it out. Don't even remember how to do trig any more.
Yo that took me like an hour and a half, I better get some sort of prize
The prize is the good feeling of a job well done.
In the biz we call that "Suckeeeeeerrrrrr."
You have defeated the evil Ponychan.
Outwitted them on every turn.
It's 50%. This is stupid.
If you flip two coins, there are four equally likely possibilities:
P(HH) = 1/4
P(HT) = 1/4
P(TH) = 1/4
P(TT) = 1/4
"At least on heads" means HH, HT, or TH.
So P("Both are heads" given "At least one is heads") = P(HH) / (P(HH) + P(HT) + P(TH)) = 1/3
I'm reasonably certain HT and TH shouldn't be considered unique instances in the context of this problem, but whatever.
Even though you have eliminated the possibility of two tails, the probability of a heads/tails mix is still double the probability of heads/heads. It's a completely different problem than saying given the first coin is heads rather than at least one of the two is certainly heads.
Yeah, I guess that makes sense. I was never any good at understanding probability.
Caught Trace in a bad mood.
I kept posting and he kept deleting.
He redirects the links he doesn't like from the site to a dead one.
