<flush> but it still not give teh awnser
<bronaugh> it's 0.52 radians.
<bronaugh> or 29.7 degrees.
<bronaugh> hm, that doesn't work out like it sholud.
<flush> i know
<flush> you know theres a formula
<flush> which says
<bronaugh> the sum of forces isn't 100N
<bronaugh> a^2 + b^2 != c^2
<bronaugh> it's 80N
<bronaugh> 80.62N to be exact.
<Lumafsck> laters
<bronaugh> later lum
<flush> (force1 + force2)^2 = force1^2 + force2^2 - 2 x force1 x force2 x cos(180-theta)
<bronaugh> if you use that value, of course it will all work out.
<bronaugh> yeah I recall that from 1st year physics.
<flush> how do i isolate theta?
<flush> with this formula, it should work fine, right?
<flush> i dont see why it wouldnt
<flush> so
<bronaugh> ok explain to me why a^2 + b^2 != c^2
<bronaugh> 100^2 = 10000
<flush> 100^2 = 70^2 + 40^2 - 2(70)(40)cos(180-theta)
<flush> you cannot make a rectangle triangle from that
<flush> you can do teh parallelogram thing
<bronaugh> ok, gotta reexamine the problem.
<flush> to add them together
<bronaugh> and turn that "teh" crap off.
<flush> lawl
<flush> k
<bronaugh> because it infuriates me.
<flush> !
<bronaugh> so in order for that to work, cos(180 - theta) must be negative... ok.
<bronaugh> so that means theta's less than 90
<bronaugh> this is so simple now.
<bronaugh> 100^2 - 70^2 - 40^2 = 2(70)(40)cos(2pi - theta)
<bronaugh> (converting to radians)
<flush> well its -2(70)(40)cos(180-theta)
<flush> but thats where i am
<flush> 3500 = -2(70)(40)cos(180-theta)
<bronaugh> so ... (100^2 - 70^2 - 40^2) / -2(70)(40) = cos(2pi - theta)
<flush> right
<flush> my question is how to take out the 180 from cos(180-theta)
<bronaugh> arccos((100^2 - 70^2 - 40^2) / -2(70)(40)) = 2pi - theta
<wamphyri> longword,
<bronaugh> 2pi - arccos((100^2 - 70^2 - 40^2) / -2(70)(40)) = theta
<bronaugh> solved.
<wamphyri> whats the deb package name for mplayer?
<bronaugh> wamphyri: it's not in deb.
<flush> -51.31781255 ?
<bronaugh> deb ftp://ftp.nerim.net/debian-marillat/ sid main
<bronaugh> flush: let me work through it.
<wamphyri> figures lol
<bronaugh> oh hell. it's pi not 2pi.
<bronaugh> so replace that
<bronaugh> 0.90 radians... so convert that to degrees...
<bronaugh> 51.317 degrees.
<bronaugh> you switched a sign somewhere.
<wamphyri> tx bronaugh
<bronaugh> wamphyri: you got that apt source added now? :)
<bronaugh> flush: anyhow, hope you're satisfied that's correct.
<wamphyri> well what you just posted lol
<bronaugh> wamphyri: good stuff :)
<flush> yeah thanks man
<bronaugh> it's really just simple algebra manipulation.
<bronaugh> what's this for? what course?
<wamphyri> grrrr
<flush> maths 1 at college
<bronaugh> wow, must be an easy course :)
<wamphyri> wth
<bronaugh> then again, I'm now a 4th year university student...
<bronaugh> gah.
<flush> hehe
<bronaugh> quit while you still can! :P
<flush> what are you studying?
<wamphyri> apt-get install mplayer-586 and i get 100 dependancy's not met
<bronaugh> flush: computer science.
<flush> niiice
<bronaugh> flush: yeah, I do pretty horribly in my math courses.
<flush> hehehe
<flush> i guess you have a lot of maths
<bronaugh> too much :(
<bronaugh> doing my last math course this term.
<bronaugh> (mainly because I screwed up)
<bronaugh> finally graduating soonish.
<bronaugh> discrete math, round 2.
<wamphyri> i just went back to school myself lol
<flush> what dya see in maths?
<bronaugh> set theory, graph theory, etc.
<bronaugh> little bit of differential equations, lots of calc.
<bronaugh> too much goddamned calculus.
<flush> lol
<flush> i heard differential is the ultimate power
<bronaugh> differential equations are... just weird.
<flush> mm
<bronaugh> I could have probably gotten OK at them.
<bronaugh> but never good
<bronaugh> I couldn't do most of the problems in my textbook to do with differential equations.
<flush> gotta be hardcore
<bronaugh> yeah.
<flush> niice
<bronaugh> couldn't do them easily; I tried for a minute or two to get it, then gave u.p
<flush> lol
<flush> nice try
<bronaugh> I'm not known for my patience.
<bronaugh> not with that kind of stuff.
<flush> ahhh
<bronaugh> I usually think I have better things to do.
<bronaugh> you drew that problem kinda wrong eh.
<flush> why that?
<bronaugh> because in you drawing the forces are orthogonal.
<flush> its just "for say"
<bronaugh> yeah, your labelling ****de... hehe :)
<flush> hehe
<bronaugh> I tohught the 40N force was along the Y axis.
<bronaugh> thought.
<flush> at least you can understand what i mean
<flush> !
<flush> thats dangerous
<purplin> he just fakes well
<bronaugh> purplin: yes.
<bronaugh> I play smart on weekends.
<bronaugh> damn, I need a better PDF viewer. evince ****s, and so does xpdf.
<purplin> try adobes, hahahahah
<bronaugh> lol
<bronaugh> yeah, I'll do that -- when a certain fiery place freezes over.
<flush> i used to read "the al-qaeda training manual" in pdf format
<flush> rofl rofl
<bronaugh> oookay
<bronaugh> yeah, when I read the Jolly Roger Cookbook it was in plain text.
<bronaugh> you kids have it easy these days.
<flush> lol
<flush> http://www.usdoj.gov/ag/trainingmanual.htm
<bronaugh> lol ok
<flush> lmao @ that
<wamphyri> kids?
<Glombrg> bronaugh what wm do you use?
<bronaugh> Glombrg: ratpoison.
<bronaugh> wamphyri: yeah, "kids
<wamphyri> bronaugh, who ya calling kids?
<bronaugh> wamphyri: flush, this time.
<bronaugh> you're next.
<wamphyri> lol
<flush> tsup?
<wamphyri> bronaugh, how old are you?!
<bronaugh> oh man, gpdf rocks evince so hardcore.
<bronaugh> wamphyri: 23
<bronaugh> hehe
