Congratulations IntensityRising

Well you guys have probaly noticed but am more active now and participating. This term is almost to a end and in math I've really brought up my grades I believe. Even though I  don't recieve report cards till a month from now, math is coming together for me. I just did the math final test today and I'm 3/4 done and its going smoothly. Btw the unit of math am on is trigganometry and pythagoras.

[Zero7]

Mmm.. Trigonometry. The EASIEST unit in math. Ever.

[Malevolent]

Trig is the most boring math class ever. I hated trig. Calculus = better.

[duherman]

My teacher taught me this.

SOH CAH TOA
Sin=Opposite over Adjacent
Cos=Ajacent over Hypotenuse
Tan=Opposite over Adjacent

you'd better remember that, because you are gonna end up using this crap alot if you ever do calculus, expecially at uni level for a comp science degree   <_<

[Dirty Harry Potter]

you can also remember it in another way, this is my way, it may or may not be useful :p. but first some snazzy ASCII of a triangle.

Tan = opposite / adjacant:
if you take tan for some degree(or radian for that matter), then you get zhe....zhe......i'll just call i "a"-value for a straight line, you know: y = ax + b.
you can also calculate this a value by divided the change in the y-values with the change in the x-values. say we could take Tan(A) from our snazzy drawing, then we get the change in y-values divided by the change x-values, being |BC| / |AC|. opposite over adjacant.

Sin = Opposite / hypotenuse and Cos = Adjacant / hypotenuse:
i just remember this by the definition of Sine, it spits out the Y-value of the point where the radius touches the circles edge.  This is also how i remember cos, since it spits out the x-value.

SOH CAH TOA

LOL did your teacher make you chant it and practically dance to it?  I remember that part of math class!!!  hahaha  :p

And I disagree, trig was always the hardest for me despite math being one of my better subjects.

Ohhh congrats IR

You realize that you basicly just told him to remember TOA SOH CAH...

[Malevolent]

But he has an ASCII triangle!

I wrote Soh Cah Toa on my calculator, I wonder if that's considered cheating on the test.

[Clashen]

We just finished that stuff, it's really easy. But the  things that comes after  it is WAY more easy, way way way.

And we got a book with all the formulas, we can have it with us to the tests and everything


EDIT: And yea, put EVERYTHING you can in your calculator. It's great to have on tests.

[snapback]41771[/snapback]

i'd count that as notes, depending on if that is allowed or not it would be cheating.

@swift.... no, no i didn't. SOH CAH and TOA is just a sentence, which you can try and remember. What i said is based on if you know what Tan, Sine and Cosine spits out, which is based on the definition of them.

[LowCrawler]

we had something like that.. if orgot the middle part but our teacher taught us

I'm to the point in calculus where I have like 50 lines of notes typed into my calculator.  :ph34r:

[duherman]

lol 50?

[SlickWill]

Trig is not the easiest math ever once it get into the realms of theoretical integrals (integrals which don't exist and you can only use trig to solve.)   If you don't thinks so, you mya feel free to some to my College and take Calc 2 with Dr. Szecsei, the hardest class I have ever taken.

[Manta]

Urgh, beginning trig is so easy if you memorize stuff, but it gets boring. Then it gets worse.

[Legionnaired]

Wait until you have to integrate(cot^2csc(theta)dtheta)

Practically you would never have to solve that, *ahemcomputersahem*.

sorry... but i found algebra pretty effing easy
