<RiskArb> seems kinda crazy, no?
<astrolabe_> 12% annually is a little bit different from 1% per month compounded monthly
<astrolabe_> but, yes, it does cost a lot to borrow money.
<astrolabe_> My top tip, is don't do it unless you really have to.
<RiskArb> now when i did the numbers
<RiskArb> i got a different answer
<RiskArb> i got $8142.59 per 6 month period
<RiskArb> which would come out to be $48,855.51$ total payment after 3 years
<RiskArb> so you pay $13,855.51 in interest
<RiskArb> which makes a lot more sense
<RiskArb> than
<RiskArb> paying like
<RiskArb> $250,000 in interest
<RiskArb> on $35,000
<RiskArb> lol
<RiskArb> 12% annual rate, even if it is compounded monthly
<RiskArb> is not that high of a rate
<astrolabe_> Yeah. You won't pay back anywhere near twice the capitol.
<astrolabe_> capital :)
<astrolabe_> my bed time. Good night.
<Safrole> For the maximum range for a projectile the best theta is Pi/4 right?
<SourceCode> think so yes
<SourceCode> i remember something like that from physics
<Safrole> sin(2*theta)
<Safrole> is the angle coefficient for the range
<Safrole> and that is maximized when theta = Pi/4
<Safrole> sin(Pi/2) = 1
<Kampen> yes, it is. that gets the furthest horizontal distance.
<SourceCode> 2*pi/4 = pi/2, sin(pi/2) = 1 yea, so it would make sense
<Safrole> I'm taking a mechanics course for the "fun" of it...
<SourceCode> haha
<Safrole> .I had the chance to take modern analysis
<Safrole> I Should have...
<SourceCode> whats ur major
<Safrole> I realize why mathematicians stay away from Physics cl***es...
<Safrole> Mathematics
<SourceCode> ahh u should have taken analysis then lol
<Safrole> I want to study quantum mechanics
<SourceCode> oh i see
<Safrole> and this cl***ical track is a prerequisite
<Safrole> so... I guess it'll be good for me in the end
<SourceCode> yea
<Safrole> these problems I'm doing aren't with numbers.. odd for physics but oh well.. for instance I'm trying to show the distance between two points that share the same height is Vo/g * sqrt(Vo^2 - 4gh)
<Safrole> when the range is maximized of course
<Cale> Safrole: that's not odd for physics actually
<Cale> Safrole: most physics is done symbolically, though I'd still complain about the level of rigour which is present in most physics. A lot of stuff is quite scary.
<Safrole> I should've taken the damn analysis course!
<Safrole> it's too late now
<dfwer> Two roads go between two towns. Road A is 200 kilometers long, and people are allowed to drive 100 km/hr. Road B is shorter, but you can't drive faster than 60 km/hr. What is the minimum amount that road B must be shorter than road A if the trip on road B is faster than road A?
<dfwer> can someone give me a clue?
<dfwer> and not answer it
<de1337> start with calculating the minimum time it would take to drive road A
<dfwer> 2 hours
<de1337> then ask yourself, if i drive 60km/h how far can you get in 2 hours
<dfwer> 120km
<de1337> then you almost got the answer
<dfwer> 80?
<sgorilla> what is a partial graph isomorphism
<de1337> yes
<dfwer> ty
<de1337> np
<zero0> hey
<zero0> i need to find a good chapter explaining the intricate detail of Jacobi theta function
<zero0> how it gets derive, how it got from quintic equation to Jacobi theta function form
<zero0> etc.
<zero0> can anyone help?
<Kampen> http://mathworld.wolfram.com/JacobiThetaFunctions.html
<dfwer> If w-1x-2 = y , what is the value of x in terms of y and w? (***ume that x, y and w are positive real numbers.)
<dfwer> can you help me?
<vIkSiT> 1x?
<vIkSiT> like 1 multiplied by x?
<vIkSiT> x = w-y-2 ..
<dfwer> If w^-1x^-2=y
<dfwer> sorry
<vIkSiT> ah
<vIkSiT> you mean (((w)^(-1x))^-2)
<dfwer> wouldn't the next step be y/w^-1=x^-2?
<dfwer> (w^-1)(x^-2)=y
<vIkSiT> dfwer, ah thats better
<dfwer> sorry
<dfwer> wouldn't the next step be y/w^-1=x^-2?
<vIkSiT> do it simply -
<vIkSiT> (1/w)(1/x^2) = y
<vIkSiT> (1/wy) = x^2
<vIkSiT> x = (1/wy)^1/2
<dfwer> why did you change it to 1/w?
<vIkSiT> w to the power of -1 is 1/w
<dfwer> oh to change to positve
<vIkSiT> you don't need to do that.
<vIkSiT> but its simpler to visualize
<dfwer> i see
<vIkSiT> more intuitive doing cross multiplication
<palomer> hello
<palomer> are there any sat solvers that accept input in NNF?
<dfwer> whats NNF?
<vIkSiT> palomer, heh, interestingly - i'm implementing WALKSAT right now :)
<vIkSiT> palomer, why nnfs though?
<vIkSiT> dfwer, negation normal form
<dfwer> oh
<palomer> vIkSiT: because I have formulaes for which I want to find satisfying interpretations
<palomer> vIkSiT: and putting these formulae into CNF would take too much time
<vIkSiT> hmm. no ideas about it. but in case you do find one..
<palomer> I want to express "only one or only three of a,b,c is true" using c only once, how can I do this?
<palomer> hrm, looks like I'm going to have to use BDDs
<glen_quagmire> is pi = acos(-1) ?
<Safrole> acos?
<glen_quagmire> arch cosine
<glen_quagmire> @math calc acos(-1)
<mbot> glen_quagmire: -(acos*calc)
<glen_quagmire> @math -(acos*calc)
<mbot> glen_quagmire: -(acos*calc)
<Safrole> you're right
<Safrole> the arccos(-1) = Pi
<glen_quagmire> this is interesting
<glen_quagmire> cos(180 degree) = -1
<glen_quagmire> an 180 degree = pi
<glen_quagmire> lol
<Safrole> Pi radians = 180 degree
<Safrole> Pi radians = 180 degrees
<Safrole> 1 radian = 57.4 degrees I believe
<de1337> @math 4*ArcTan[1]
<mbot> de1337: Pi
<Safrole> 54.37 or something...
<RyuKojiro> How can I differentiate sin x + cos y = sin x cos y ?
<Safrole> partially?
<RyuKojiro> implicitly, and completely
<GRedner> RyuKojiro: with respect to which variable?
<Safrole> it's implicit differentiation
<RyuKojiro> I can only get to cos x - sin y = cos x cos y - sin x sin y
<RyuKojiro> GRedner: y' implicitly
<tyler-> hey, can anyone in here tell me what the sum from 1 to n of 1/n is?
<Alija_> what the sum ?
<Alija_> what does it mean
<tyler-> 1 + 1/2 + 1/3 + 1/4 + .... + 1/n
<kelt> tyler-: it is infinity.
<kelt> oh...
<tyler-> hrmm
<kelt> n(n+1)/2
<kelt> thought you were talking about the harmonic series :)
<tyler-> that's the sum from 1 to n of n
<kelt> yes.
<tyler-> I'm looking for 1/n :)
<Ayoze> infinity
<Alija_> why infinity
<tyler-> how is n not infinity then? 1/n is smaller.....
<kelt> hmm... let S = 1 + 1/2 + 1/3 + ... + 1/n
<tyler-> basically
<tyler-> I'm analysing an algorithm
<kelt> I think it is 1/(1 - n)
<tyler-> where my prof had SUM(i=1 to n) 1/n * i
