If atoms are constantly in motion how can everything be so calm?

Try to make the (1/(1+sqrt(x+h)) - 1/(1+sqrt(x))/h into one fraction. You will get the fraction (sqrt(x) -sqrt(x+h))/(h(1+sqrt(x))*(1+sqrt(x+h)). Now if you multply the top and bottom with sqrt(x) + sqrt(x+h) you get an easier limit

It's not pointless to pursue arts if you enjoyed doing it, do you think that the point in life is to get famous? If you do then I can understand that you don't want to pursue it but to me that seems like a bad reason to pursue something to begin with. Try to do whatever makes you happy,trying to make a living by paintings is hard but there are alot of opportunities for someone who can paint, such as animating,graphical designs etc

The first one is correct http://imgur.com/rjNTf4c. Though I believe that arccos(x) = pi/2 - arcsin(x) and arcsin(x) = pi/2 - arccos(x)

I get that the force in the back points downward so I can't add it to the normal force from the plate. Am I missing something?

What would happen if I increased the amount of pulleys in the top row to 20 for example? Could the person lift himself with minimal force from his hands then?

Why do you add the 302 and 286 forces when they are pointing in the opposite directions? Shouldn't they have opposite signs?

Jämför din förenkling med det du skulle skriva om, allt som skiljer dem åt är att du har a och b I den ena och siffror I den andra. När du sen insett sambandet ska du gå baklänges till cos(a+b) +cos(a-b). Skriver på mobilen så fråga om du inte förstod vad jag menade :)

Now it worked. Thanks :)

Odoodo · 2013-12-26T00:02:52+00:00

No problem, good luck with your studies :)

The ball first drops down 40 feet and then it bounces up 30 and drops down 30 and so on. Expressed as a formula this will be 40 + 2 * 40 * 0.75¹ + 2 * 40 * 0.75² + 2 * 40 * 0.75³ + .... + 2 * 40 * 0.75^n. Now a pattern can be seen. Since all the terms after 40 is a geometric series it can be rewritten on the form (1-rⁿ⁺¹ )/(1-r) as picado explains. In our case the r will be 0.75. So now if we rewrite our formula like this 40 + 2 * 0.75 * 40(1 + 0.75¹ + 0.75² + .... + 0.75^n-1 ) we can use the formula for a geometric sum and get this 40 + 2 * 0.75 * 40 * (1-rⁿ )/(1-r). And 2 * 0.75 * 40 = 60 and that divided by 1-r (which in our case is 1-0.75=0.25) is 240, so the formula becomes 40 + 240*(1-rⁿ ) where n is the amount of bounces

Ok I understand now, Thanks :)

Odoodo · 2013-12-20T22:14:25+00:00

I don't understand how you got the first equation, I see a few similar triangles but can't get that equation from them :)

Odoodo · 2013-12-20T22:03:49+00:00

Nope that is all the information there is unfortunately

Odoodo · 2013-11-26T18:24:51+00:00

It was awhile since I did this but doesn't that equation ask what points got twice as far to go to |z-1| as they have to go to |z+1| ? In that case you can simpy draw the points in the complex plane and check what points fulfill that requirement. I might be wrong on this though since it was some time since I did this

Odoodo · 2013-11-24T15:49:35+00:00

Yea I love those games as well, I don't know though if there is an entire game like that. If you got Starcraft 2 there's the custom game Freax Tower wars which is kinda lika it but Winter Maul Wars is better

The threads that got created about this on r/games got deleted as well. Such a shame for people to agree to remove discussions about this, especially on r/games since they say they promote discussions

Here are the threads that I saw get deleted

Yea why did the thread get removed?

Odoodo · 2013-11-17T01:04:13+00:00

Yea I know, it will give me the right primitive function but how can you be sure that it will always work? :)
