remember..."SOH, CAH, TOA"
That's Chief Sohcahtoa to you, pal. :D
i just took end of year trig exams today.
and my teacher told us that too.
I'm taking a trigonometry exam tomorrow, and something just occurred to me: At any time during class, did anyone ever learn what Sine or Cosine or Tangent actually meant? Now that I think about it, I don't think it ever happened... weird. Anyway, yes, Trig sucks and is a complete blur, but at least... um... huh, I don't think I can end that sentence honestly. :P
I took trigonometry last year. Not fun. I've always wondered what cos sin and tan are. And I've heard there is a fourth, a cotangens. *shivers*
The English "sine" came about through quite a convoluted path. It started with chords (a straight line drawn though two points on a curve). The Sanskrit word for chord-half was jya-ardha, sometimes abbreviated as jiva. Arabic mathematicians translated it as jiba, written sans vowels as jb. Due to a hilarious mistranslation into Latin, the word sinus was chosen to translate jb, believing it to be jaib, Arabic for breast. English shortened it to "sine".
So, now you know. Sines are breasts. (Would that make cosines a pair?)
"But the graph goes through the origin" and you are point at ... an asymptote?!
Nuuuuuuuuuu teh horrors!
omg... SOHCAHTOA... i just had an exam on that a week ago lol... and cotangent? wth? is that like tan/cos?
. . . you learned Trig in 8th grade?
No wonder I'm so far behind. >.<
I'm a pretty good writer, but I'm a mathematical moron. I got a C- in Algebra II in 11th grade, and I have a feeling the only reason I got an A in Geometry is because it was the teacher's first year teaching.
And once again, I am so glad I am a business major.
lol Nice eighth-grade hair. XD I can't even really tell what style it is...
Your drawings remind me a lot of a friend's. ^-^ Very cute.
are those wrinkles on your teacher or a mustache?
Did the teacher wear Google Glasses? ;)
triangles are like the most important shape in the universe!
FFFFFFFFFFFFFF foil turkey.
Well I fail Maths.....terribly.
But its bcuz im lazy. XD
It's funny, my trig teacher actually *did* say that...
