hia, Im very curious to have a squiz througjh the java.lang.object class, I've noticed in netbeans you can ctrl+ click various keywords / methods to take you directly to the file where its defined

How can I access the java.lang.object class in Netbeans (or any other IDE)? are the JDK files write-protected by default?

Hello, I recently got a "full HD" TV /monitor. The box specified 1920x1080, but windows lists 1280x720 as the recommended / "native" resolution. I've physically counted the pixels of a 10x10 block and know that it is indeed 1920x1080, but the text appears a little blurry (even worse in interlacing mode) and much crisper at 1280x720. After reading up on it, there seems to be a simmilar concern with retina display macbooks

My question is basically threefold;

* what is pixel doubling?

* if a screen is physically capable of showing a full resolution, why would the native/recoomened resolution be lower?

* are there additional tricks I can do to make text more readable? (so far I've tried scaling windows text 100/125/150, tweaked sharpness/brightness/contrast, changed refresh rate - most of which have helped but its still not quite there)

Is it possible to get married without legal recognition - that is, without signing a marriage certificate? And if so so, in the event of a "divorce" would the co-dependent spouse be entitled to anything? or would every asset belong to whoever it belonged to before the "marriage" ?

ps. Im interested in this preferably from an Australian law perspective (American / Cannadian / British / New-Zealand / other western nations would also be of interest)

Hello, ive got a specific case in mechanics where there are to versions of an equation basically it comes down to; for the vectors a & b does the vector cross product:

a x (a x b) = ||a||²b

hold valid as a property in general? In the formula, the vector a is an angular velocity typically with only one k component.

I mean, isn't ampere just a conjunction of two more fundamental units: charge / second? Is it just an abnormality or is there a reason behind this?

Hey, doing a quick refresher on a bit of linear algebra and need to know if the following 2 statements are true for some matrix A:

a) if the determinate of A equals zero aka. det(A) = 0 ~ does this mean the matrix is linearly dependant

b) if the determinate of A is not zero, is it ALWAYS linearly independant?

how do you test for linear independance? unfortunatly im a little rusty

I've been struggling with a particular course all semester averaging a failure grade, now I have an exam in 2 weeks worth 70%. To anyone who's been in this situation before - how difficult is it to learn this type of content in a short timeframe? I find the mathematics fine, but the concepts and theory very challenging and I dont seem to be learning well from textbooks.

Im interested to know if anyone knows of any helpful free or purchasable online video content that covers mechanics - specifically second year statics with content such as mohrs circle, shear flow, yield crieterons, failure, impact, stress & strain etc. Also any tutoring links would be handy

in an ordered pair you have (x,y) where x is the abscissa and y is the ordinate. If the pair is (x,y,z) does the z term have a special name to? If so what is it?

Hi, Im wondering what the relationship is between the Hooke's law I learnt in physics for a spring:

F = -k x (Force = -springconstant * displacement)

..and the Hookes law Im now learnt / am learning in mechanics for a stress / strain relationship:

σ = E ε (Stress = Youngsmodulus * strain)

I don't really have a good understanding of tensors, but am hoping there is a relatively easy way to see what the relationship is?

Hi, just wondering, what are the units for v in this formula (mass-energy equivalence / mass in special relativity formula?)

http://upload.wikimedia.org/wikipedia/en/math/6/3/...

where m is in kg

and c is in km/s or m/s

are the standard units for v m/s, km/s or something else?

... similarly, would you need n-1 eyes to have depth perception in a world with n spatial dimensions - would those eyes each need to extend into their own linearly independent dimension, or do you suppose our brain could just create assumptions and work with 2 eyes?

Ok so I have 2 websites that I recently transferred to my on home server and so far I hav'nt been able to manage setting up nameservers on windows XP. The domains are being forwarded & asked at the moment, but as I understand, this will adversely affect my sites SEO.

The main question i have is; will a search engine cache/crawl my site if the domain name is unmasked? ie once you type in the domain it will go to the ip of the site. Alternatively is there a relatively simple / free way to setup a nameserver or two on my machines at home (for a WinXP WAMP server)?

Ok, so the equation of an eliipse with horizontal radius: a, vertical radius: b and center (h,k) is;

(x-h)²/a² + (y-k)²/b² = 1

Find an equation of the ellipse with center at the origin that passes through the points (1, (-10√2)/3 ) and (-2, (5√5)/3 )

I keep getting non-real answers which would suggest theres no solution. Drawing it suggests there could be up to 2 solutions, but i dont know why theyd put in such ugly numbers resulting in no solution.

Show that the sum, difference and product of rational numbers are rational numbers.

Im puzzled as to why sqrt(x)^2 =/= abs(x) for x is complex.

According to wolfram, the sqare root,squared of -i is -1

...but the absolute value of -i is 1

Why is there a difference?? And why do i get a math error when i put (√(-i))² into my handheld casio calculator?

notes: sqrt(x) = square root = √x

abs(x) = absolute values = |x|

Which of the 3 graphs best describe an ice cube melting in a room and why? Would the rate be any different if the ice cube was melting in a glass of water?

A basic guess would be a straight line (B), but then consider - it might speed up as the volume decreases as theres less cold mass to retain its form (C) ~ further still, is it possible that it decreases rapidly at first but then levels off as it approaches the temparature of the room (A) ? Its a bit quirky, but I'd like to know the answer to this - the more in-depth the better :)

By using Green's theorem, evaluate

∫y^2 dx + 5xy dy

where C is the boundary of the semi-annular (semi-circle) region D in the upper half of the plane between the circles x^2 + y^2 =4 and x^2+y^2 = 16

by applying greens theorum I get ∫ ∫ 3y dA

but i dont know how to properly convert the thing into polar coordinates (or if thats even what im supposed to do next). I can see by drawing that

2 < ρ < 4 and

0 < θ < π

..but am lost on what to do to the 3y to convert to polar: does y become ρsin(theta) or something?

Just curious to know if there exists a known case where a women has been prosecuted over this?

Also,can marital rape can occur in same-sex marriges with two females - and if so, what exactly would constitute "rape" in that scenario.

∫ sqrt(2-2cos(x)) dx

apparantly making a substitution for;

u = 2 - 2cos(x)

du = 2sin(x) dx

gives:

∫ sqrt(2-2cos(x))

= ∫ {-1 / sqrt(4 - u) } du

..but i cant see how, im guessing theres some obscure trig identity and cancellation im not seeing? could somone explain this stage a little better please.

(click show steps for better notation, in particular - the substitution bit)
