I see lot of people cut and paste Yahoo answers. Can some one explain it to me, step by step, as to how this done?

I had chosen:

u = arctan x dv = xdx
du = 1/(x^2 + 1) dx v = x^2/2

= xarctanx - 1/2 * S x^2 / (x^2 + 1) dx //applying udv - Svdu
= xarctanx - 1/2 * S 1 - 1/(x^2 + 1) dx //applied long division
= xarctanx - 1/2 [x - arctanx] //took integral
= xarctanx - 1/2x - 1/2arctanx

Is this right?

Why would you expect to hear more arguments about the validity of using statistics then the validity of using probability? This is a bio lab question and I'm stumped.

How much would a half decent telescope cost? And not being too expensive. And are they worth wild, can you see much interesting things with them? Would love to get into that hobby, and feedback would be great. Thanks.

I would like to know; What is the relationship between watts/square centimeter, and the boiling point of water for system pressures between 0 and 40 psi. Also, I'd like to know what the relationship of water flow past the heating element would be for energy densitys above the boiling energy density. Specifically, if I use a heating element that has a watt density above the boiling poine (at 0 pressure), how much flow (past the heating element surface) do I need for various energy densities to not have boiling?

Thank you

I was asked of why is the equator of Earth is made 0 degrees. I know that it's an imaginary line, therefore it's only defined as 0 degrees by people. But why?What are some of the mathematic and scientific reasons?

A 95% confidence interval estimate for a population mean was computed to be (44.8 to 50.2). Determine the mean of the sample, which was used to determine the interval estimate.

Yeah, a lot of them do fly south for the winter, but some don't. For example, there are some annoying pigeons who hang around the roof across the street. Temperatures have been well below freezing, with wicked wind chill, for the past couple of weeks!

ok, this is from another part.


area of cube on one side is 1 sq cm.

area of cube on all sides combined is 6 cm squared

volume of the cube is 1 cm^3

mass of cube is 1 gram



Ok, here is the questions, can you create a larger cube that is twice as large (2 cm on each side) than the above.


area of cube on one side is ?

area of cube on all sides is ?

volume of the cube is ?

mass of cube is ?


what would the sketch look like then?

Imagine if someone says that they could only understand love if they can put it into some kind of scientific formula, or measure it out to prove it experimentally? “Science “can tell us little about the appreciation of a sunset, about the soul of man or so many other things. For that matter, science can tell us very little about the mind itself.



The thing is, science can only begin after the universe and the creation already exist. Science can tell us nothing about what happens before that. In fact, let me say this; science begins after creation. The first law of physics, conservation of matter and energy says matter and energy can neither be created nor destroyed. This tells you that science does not know how matter came into existence. It should also tell you that if matter cannot be created under the laws of this universe, that something outside the 1st law created matter and energy. The most important law of science itself points to a “special creation” outside of science
