Best ResponseYou've already chosen the best response.0So, you cannot have COS 23pi/6 = 12.03

Best ResponseYou've already chosen the best response.0\[\cos\frac{23\pi}{6} = \cos(3(2\pi) + \frac{5\pi}{6}) = \cos\frac{5\pi}{6} = ...?\]

Best ResponseYou've already chosen the best response.0Using the attached drawing where does 23/pi fall?

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

Lethal

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

Best ResponseYou've already chosen the best response.0so i subtract 2pi fom 6?

nelsonjedi

Best ResponseYou've already chosen the best response.02pi = 12pi/6..So 23pi/612pi/6 = 11pi/6

Best ResponseYou've already chosen the best response.0Are you familiar with the unit circle in trigonometry?

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

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

Lethal

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

Best ResponseYou've already chosen the best response.1That gives us 330 degrees

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

Best ResponseYou've already chosen the best response.1hint: It's in quadrant IV

Lethal

Best ResponseYou've already chosen the best response.1Okay. tell me the coordinates for it.

Lethal

Best ResponseYou've already chosen the best response.1That would be 315 degrees.

Lethal

Best ResponseYou've already chosen the best response.1Okay. You should know that Cosx= x

Lethal

Best ResponseYou've already chosen the best response.1So what is the value for Cos330?

Lethal
 one year ago
Best ResponseYou've already chosen the best response.1Keep this exact. You just gave me the coordinates. and I just told you CosƟ=x

Lethal
 one year ago
Best ResponseYou've already chosen the best response.1so what is the exact answer?

Lethal
 one year ago
Best ResponseYou've already chosen the best response.1Use the coordinates you gave me.

Lethal
 one year ago
Best ResponseYou've already chosen the best response.1Yes and I told you cosƟ=x so what is cos330?

ygarcia

Best ResponseYou've already chosen the best response.0I don't get it /.\ I'm sorry

ygarcia

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

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

Best ResponseYou've already chosen the best response.1ygarcia what calculator are you using btw?

ygarcia

Best ResponseYou've already chosen the best response.0I don't have a calculator

Lethal

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

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

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

Lethal

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

Lethal
 one year ago
Best ResponseYou've already chosen the best response.1Very 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.

ygarcia

Best ResponseYou've already chosen the best response.0So Cos= x value and Sin= y value?

Best ResponseYou've already chosen the best response.0In reference to the circle

Lethal
 one year ago
Best ResponseYou've already chosen the best response.1Yeah. 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.

Best ResponseYou've already chosen the best response.0Okay, Thanks SO MUCH!!!! I don't fully get it yet but what you explained to me helped A LOT :)
