Best ResponseYou've already chosen the best response.0I don't know why I'm forgetting how to do this, but it's been awhile and my final is coming up and I want a better understanding of it.

Best ResponseYou've already chosen the best response.1when you at look the unit circle what quard would Sin be in?

MrCarey

Best ResponseYou've already chosen the best response.0I see that it goes 11π, so I believe it's going clockwise around the unit circle and I think it gets to Q3.

godorovg

Best ResponseYou've already chosen the best response.1yes correct, so in the problem what does that tell you?

MrCarey

Best ResponseYou've already chosen the best response.0I don't know...hahaha, rephrase that maybe?

godorovg

Best ResponseYou've already chosen the best response.1from looking at this problem and taking the information you already have what would you say the answer is? sin(arcsin(11π/13)

godorovg

Best ResponseYou've already chosen the best response.1do you understand arcsin and what that means??

MrCarey

Best ResponseYou've already chosen the best response.0crap, I wrote it down wrong. It was arcsin(sin(11π/13))

MrCarey

Best ResponseYou've already chosen the best response.0I have a pretty good understanding of how to use it. I'm rusty, though.

godorovg

Best ResponseYou've already chosen the best response.1okay, let us take this and break it down on what you know, you start I will fill in if needed.

MrCarey

Best ResponseYou've already chosen the best response.0I believe sin(ø) = arcsin (11π/13) in this situation.

godorovg

Best ResponseYou've already chosen the best response.1you are right, but how did you do that?

MrCarey
 2 years ago
Best ResponseYou've already chosen the best response.0I just kind of have that memorized. I guess I never really grasped that...

godorovg

Best ResponseYou've already chosen the best response.1okay, now I have a stupid what is the question asking for??? I am a little lost with the question here does it ask to solve or what?

MrCarey

Best ResponseYou've already chosen the best response.0Find the exact value of the given expression. Simplify your answer (rationalize the denom)

MrCarey

Best ResponseYou've already chosen the best response.0I also have that the answer is 2π/13

MrCarey
 2 years ago
Best ResponseYou've already chosen the best response.0I don't really understand where the 2π comes from.

godorovg

Best ResponseYou've already chosen the best response.1because recall the unit circle has a total of 360 degrees right?

godorovg

Best ResponseYou've already chosen the best response.12/pie is a point on the Unit the circle in which the angle is 360.. you beat to that one good job

MrCarey

Best ResponseYou've already chosen the best response.0So, my picture shows the line 11π/13 and the distance between that line and the 180º line is 2π/13.

MrCarey
 2 years ago
Best ResponseYou've already chosen the best response.0Having a hard time understanding why it's 2π and not just π.

MrCarey
 2 years ago
Best ResponseYou've already chosen the best response.0Probably just overthinking it.

godorovg

Best ResponseYou've already chosen the best response.1what I am questioning here the negative here in this case?

godorovg
 2 years ago
Best ResponseYou've already chosen the best response.1because you start with a negative you will most likely end that way..

godorovg
 2 years ago
Best ResponseYou've already chosen the best response.12pie is at the 360 degrees which has points 0,0 so how can that be a negative result help here?

MrCarey

Best ResponseYou've already chosen the best response.0One sec, gonna post a photo of what is giving me a headache.

godorovg
 2 years ago
Best ResponseYou've already chosen the best response.1I think we are both getting the same headache on this. This problem is going down..

MrCarey
 2 years ago
Best ResponseYou've already chosen the best response.0Hahaha, I'm tellin' you. I haven't had any problems with any other questions, but this one is just destroying my brain.

godorovg
 2 years ago
Best ResponseYou've already chosen the best response.1yeah, the same thing only that my brain is dead because I am stuying Vectors myself.

Best ResponseYou've already chosen the best response.1what I am missing here????

lgbasallote

Best ResponseYou've already chosen the best response.1is the question still \[\sin (arcsin (11 \pi/3)\]

godorovg

Best ResponseYou've already chosen the best response.1yes sir, please help me I am getting a major headache here

MrCarey

Best ResponseYou've already chosen the best response.0Messed up the on the original post

lgbasallote

Best ResponseYou've already chosen the best response.1here's a hint.. arcsin( sin x) = x sin (arcsin x) = x cos( arc cos x) = x arc cos (cos x) = x tan (arctan x) = x arctan (tan x) = x does that help?

MrCarey

Best ResponseYou've already chosen the best response.0There is the picture that I was trying to describe.

MrCarey
 2 years ago
Best ResponseYou've already chosen the best response.0I wish that helped, but I still can't figure out why it is 2π/13

lgbasallote
 2 years ago
Best ResponseYou've already chosen the best response.1is that included in the question? or is that your solytion?

MrCarey
 2 years ago
Best ResponseYou've already chosen the best response.0Solution. It's an answer key and I'm trying to decipher it.

MrCarey
 2 years ago
Best ResponseYou've already chosen the best response.0I know it is 2π/13 because of the range, but I don't know where the 2π came from.

lgbasallote

Best ResponseYou've already chosen the best response.1use the hint i gave you...here's a demo \[\sin (\sin^{1} ( \frac{\pi}{2} ) ) = \frac{\pi}{2}\] \[\sin^{1} (\sin ( \frac{2 \pi}{5} ) ) = \frac{2 \pi}{5}\] getting it now?

lgbasallote
 2 years ago
Best ResponseYou've already chosen the best response.1\[\sin^{1} (\sin ( \frac{11\pi}{3} ) ) = \frac{11\pi}{3}\] then simplify that you get \[\frac{2\pi}{3}\] make sense?

godorovg

Best ResponseYou've already chosen the best response.1lgbasallote what did I miss here? I mean I thought for sure I was going the right way what did I do in my steps that went wrong here? Help me to understand..

MrCarey
 2 years ago
Best ResponseYou've already chosen the best response.0How'd you simplify to that?

lgbasallote

Best ResponseYou've already chosen the best response.1i think i wrote the wrong thingies lol...

lgbasallote

Best ResponseYou've already chosen the best response.1but that's the concept

MrCarey
 2 years ago
Best ResponseYou've already chosen the best response.0Yeah, I knew what you were saying with the others. It's this deal here. I don't understand how it is simplifying from 11π to 2π.

MrCarey

Best ResponseYou've already chosen the best response.0It's like it just magically disappears.

MrCarey

MrCarey

MrCarey

Best ResponseYou've already chosen the best response.0Nope, this one seemed to be the only one I kept coming back to. This stupid thing made everything else seem easy!

godorovg

Best ResponseYou've already chosen the best response.1yeah, I only hope for me it is just one problem that will allow everything to be easy after that. Fat chance ha ha

MrCarey

Best ResponseYou've already chosen the best response.1funny you just posted MIT, Because I am using thier open courses on line for the video in math and Physics

MrCarey

Best ResponseYou've already chosen the best response.0Haha, that works, too! You'd probably like his teaching style. He is very helpful and has tons of videos. I always recommend the site.
