I need a few answers....
using identities find the values
1. sin* = -6/7 , find cos*
2. sec^2 pie/12 - tan^2 pie/12
for # 2 i think you have to deo something with the equation cos^2 X = 1 - sin^2 X
Find exact value
3. cos* = -12/13 , angle (*) in quad III
4. Tan* = -3 , cos *>0
I remember that stuff, not enough to help though. I'm so glad they teach such useful things in school.
My brother and I were brutal. I once chased him around the house with a spoon that I put on the burner. I burned that little pricks leg. -sharkall2003
Then I saw a little african boy sleeping, and I thought...that is little Okeke. he is tired from herding all the goats and the big goat got away today - Rock
Do you just want exact answers? What do you mean by "cos*" ? What's the * for?
i'm not gonna look at all that
that usually will help you figure most trig
You spelled pi "pie". You do not deserve my assistance.
* = angle
sin angle = such and such
and pie/pi....its been a long day at school...project due tomorrow morning and teacher cant speak english or teach

and as was stated * = the angle

Okay, well, if sin theta is negative, theta is in quadrant 3 or 4.Originally Posted by accuFLEX
Constructing the reference triangle, the sides are as follows:
Adjacent: Sqrt(49-36) = Sqrt(13)
So, if theta is in quadrant 3, cos theta is negative sqrt(13)/7
If theta is in quadrant 4, cos theta is positive sqrt(13)/7
This is just the pythagorean identity. It is identically equal to one. You need to learn your identities.Originally Posted by accuFLEX
Use cos theta = 12/13 to find the reference angle, then add it to 180 degreesOriginally Posted by accuFLEX
Tan is negative in quadrants II and IVOriginally Posted by accuFLEX
If cos is positive, this eliminates quadrant II
Since tan theta = -3, the reference triangle has opposite = 3, adjacent = 1, hypoteneuse = sqrt(9+1) = sqrt(10)
Cos theta is adj/hyp, and positive.
E = MC^2
Really though....What are you taking? 0.o
Built...wow...you really do know everything
Google knows everything.Originally Posted by accuFLEX
Don't hate the player. Hate the game.
So, you're saying that google is just Built in disguise?Originally Posted by MM

You get play from the girl of your dreams

Hit up some fun with the guys
Then get more play (all in one afternoon/evening I might add.. S)
You are a success my friend . Share your secrets. (Crippy)
As for the weight gain, that too shouldn't be a problem, just tell them your leaning out. Then flex your bi and tell them to ****ing get lost.
yeah or throw something at them

Built, you're a mathmatician?
Yeah, its just trig, its not too bad. Built answered everything already.

Ew, I hate being a geek. I started to work it out without thinking. Thanks for giving the answers and relieving me from doing it on my own, Built.
So, if I put questions about Linear Algebra up here next semester would you answer those too?
Use a calculator. Thats what they are for.
Seriously, if you are looking into a career that in anyway uses math, I would just bite the bullet and learn this stuff. Its soooo basic, that if you don't learn it now, when you get to the harder stuff, you'll never make it.
its easy to say "just learn it" but i have little to no notes on this stuff. My teacher cant speak english. I can post a sound clip of him if you want me to (just need to know where i can host it)
Are there any good sites for this type of math?
