so I replace pi with 180?
 3 months ago

ygarciaBest ResponseYou've already chosen the best response.0
so it'd be 23*pi divided by 6?

can you please explain?

So, you cannot have COS 23pi/6 = 12.03

\[\cos\frac{23\pi}{6} = \cos(3(2\pi) + \frac{5\pi}{6}) = \cos\frac{5\pi}{6} = ...?\]

Using the attached drawing where does 23/pi fall?
 3 months ago

LethalBest ResponseYou've already chosen the best response.1
Okay sir's let me tell you that. Cos23pi/6 2pi will give you the same answer
 3 months ago

LethalBest ResponseYou've already chosen the best response.1
The reason you don't know where it falls is becomes you have to do more than one revolution around the circle

ygarciaBest ResponseYou've already chosen the best response.0
so i subtract 2pi fom 6?
 3 months ago

nelsonjediBest ResponseYou've already chosen the best response.0
2pi = 12pi/6..So 23pi/612pi/6 = 11pi/6

Are you familiar with the unit circle in trigonometry?
 3 months ago

LethalBest ResponseYou've already chosen the best response.1
Now if radians are bothering you we can convert it to degrees.

ygarciaBest ResponseYou've already chosen the best response.0
do i need like a specific calculator for this?
 3 months ago

LethalBest ResponseYou've already chosen the best response.1
You could plug this into your calculator, but if this comes up on a test and you can't use one, you will be screwed.

ygarciaBest ResponseYou've already chosen the best response.0
Can you explain how to do it manually?
 3 months ago

LethalBest ResponseYou've already chosen the best response.1
That gives us 330 degrees
 3 months ago

LethalBest ResponseYou've already chosen the best response.1
Do you know where that is on the unit circle?
 3 months ago

LethalBest ResponseYou've already chosen the best response.1
hint: It's in quadrant IV
 3 months ago

LethalBest ResponseYou've already chosen the best response.1
Okay. tell me the coordinates for it.
 3 months ago

LethalBest ResponseYou've already chosen the best response.1
That would be 315 degrees.
 3 months ago

LethalBest ResponseYou've already chosen the best response.1
Okay. You should know that Cosx= x
 3 months ago

LethalBest ResponseYou've already chosen the best response.1
So what is the value for Cos330?
 3 months ago

LethalBest ResponseYou've already chosen the best response.1
Keep this exact. You just gave me the coordinates. and I just told you CosƟ=x
 3 months ago

LethalBest ResponseYou've already chosen the best response.1
so what is the exact answer?
 3 months ago

LethalBest ResponseYou've already chosen the best response.1
Use the coordinates you gave me.
 3 months ago

LethalBest ResponseYou've already chosen the best response.1
Yes and I told you cosƟ=x so what is cos330?
 3 months ago

ygarciaBest ResponseYou've already chosen the best response.0
I don't get it /.\ I'm sorry
 3 months ago

ygarciaBest ResponseYou've already chosen the best response.0
when I plug in Cos330 it gives me the decimal I gave you
 3 months ago

LethalBest ResponseYou've already chosen the best response.1
Okay also cosƟ=A/H This is the unit circle and the hypotenuse will always be one so basically cosƟ=H what is Cos330?
 3 months ago

LethalBest ResponseYou've already chosen the best response.1
ygarcia what calculator are you using btw?
 3 months ago

ygarciaBest ResponseYou've already chosen the best response.0
I don't have a calculator
 3 months ago

LethalBest ResponseYou've already chosen the best response.1
Okay. Well just finish it. Cos330=A. What is A in that triangle? A for adjacent to theta.
 3 months ago

LethalBest ResponseYou've already chosen the best response.1
No. Adjacent means next to. So what is next to theta that isn't the hypotenuse. 1/2 is opposite.

ygarciaBest ResponseYou've already chosen the best response.0
so the solution is sqrt 3/2?
 3 months ago

LethalBest ResponseYou've already chosen the best response.1
Now let's see if you learned anything. Tell me the sin330 if you know that sinƟ=y
 3 months ago

LethalBest ResponseYou've already chosen the best response.1
Very good. Just use the coordinates you gave me for that degree value. (sqrt(3)/2, 1/2) (x,y) SinƟ=y and the y value for 330 is 1/2 so that's the answer.
 3 months ago

ygarciaBest ResponseYou've already chosen the best response.0
So Cos= x value and Sin= y value?
 3 months ago

ygarciaBest ResponseYou've already chosen the best response.0
In reference to the circle
 3 months ago

LethalBest ResponseYou've already chosen the best response.1
Yeah. Because in the unit circle the radius is one, that's why it's called a unit circle, one unit. Anytime you have something over 1 It's just whatever the numerator is.

Okay, Thanks SO MUCH!!!! I don't fully get it yet but what you explained to me helped A LOT :)
