SOH=Sine=oposite over hypotenuse CAH=Cosine=adjacent over hypotenuse TOA=Tangent=opposite over adjacent
I think? Geometry has been....16 years ago.

[NAFDA] Spike-centric discussion. Lusty, lewd (only occasionally crude), risqué (and frisqué), bawdy (Oh, lawdy!), flirty ('cuz we're purty), raunchy talk inside. Caveat lector.

Sir, it's not an offence to let your cat eat your bacon. Okay? And we don't arrest cats, I'm very sorry.
Oh, that makes sense.
I would just picture the triangle in the unit circle in my head. And remember that tan(π/2) was undefined, so cos(π/2) had to be zero. So then sin was the vertical one and cos the horizontal one.

Yeah, whereas I'm going "OK, but...I don't remember WHY you would need the sine or tangent of anything..."

'Cuz trigonometry kicks ass!!

And that's easier? Wow.
Mind you, since I never took trigonometry, I have to kind of laboriously construct the whole unit-circle thing in my head, and figure out where the right angle goes and all that, and it certainly doesn't come naturally.
meara, if you know a couple things about a right triangle and need to find something else, basically. In this case, we knew what one of the angles was, and we knew what the length of the hypotenuse was supposed to be, but the program would only let us set the length of one of the other sides, so we had to figure out what that should be in order for the hypotenuse to be the right length. If I could draw a picture, you'd totally know what I meant.

I would always forget which was which for sin and cos. I knew tan was the ratio of sin/cos, and I thought undefined results were cool (at some point we had to graph tan x for x=0 to 2π or something)....

Every now and then, I think I might actually be a little odd.
Yeah, when those trig questions come up for me, I just... oh, wait. That never happens.
Tonight I'm gonna have that nightmare where I'm in geometry class and I don't know any of the answers.

The other night I had that nightmare were I was running for Congress but forgot to campaign.
OK, not really a nightmare. But I ended up losing. To my brother.
