How to do this? @magbak http://prntscr.com/3le6pr
I am here
How we always do things... with MAGIC :D
and just coz "I'm curious" and all that, incidentally, do you know what the sine of \(\large \frac{4\pi }{3}\) is?
Nope. I know absolutely nothing /.\
Well that's not true... for one thing, you know I'm absolutely awesome :3
I am working on it
So the csc of this? \[\frac{- 2 }{ \sqrt{3} }\]
*is this
no...
am i close though?
it is greater than that
Where did you even get \[\Large \frac{-2}{\sqrt 3}\]
It is D
the last option
I got that because you said the csc is the reciprocal of sine...........
Yes, but you don't have that in your choices :) Rationalise :D
I know because when I graph it it ends up being this
it is the reciprocal of sine yes but it is not related you need to evaluate and evaluate means find the exact solution
haha don't be silly, you cannot evaluate csc without knowing the sine :3
I did that and I got the correct answer or is my answer invalid?
Oh yea peter you cant have a square root in the denominator
Just because you get the correct answer doesn't mean your method is correct :) I could say I got the correct answer by looking at a bloody crystal ball, I get the correct answer, but what matters is the method :) Now, you can't graph functions like these with the precision of a computer, unless you have one at your disposal ^.^
oh yeah alley, multiply by \[\Large \frac{\sqrt 3}{\sqrt3}\] to rationalise.
qwll I have a graphing calculator and most Algebra 2 students are required to have 1
peace, @magbak let's not discuss it any further... also, to be fair, you DID just give out the answer, which isn't allowed on openstudy... stay your excitement next time, ok? :)
i can use Geogebra or a graphing calculator or i can use the graphing calculator to evaluate for me there are somany ways to find the answer without the hassle that converting to sin has.
So it would be this? \[\frac{ -2\sqrt{3} }{ 3 }\]
Sorry @PeterPan i ment no harm and i apologize was just trying to help.
yes
lol @magbak, I said let's not discuss it any further, but since you insist... I strongly believe simply KNOWING what the sine of the angle is and then just taking a reciprocal... has far LESS hassle than having to open up some software and/or a graphing calculator... just your pen necessary, right? :/ Oh well, good job, Alley :)
sincere apologies my fine sir.
Thanks guys ;)
I have a few more want to help?
No prob bae tag me if you need more.
