Ok, thanks for the tip. In that case, I will probably not be able to put this integral to any good use, as I am not familiar with most non-elementary functions. Thanks anyway.

Well, to be honest, all I can seem to do is stare at it. I can't factor it, clearly, to get it separated into parts so that I could even attempt to do int. by parts or anything of that sort. I have tried Wolfram online integrator, but that doesn't work because it takes the server too long to...

This integral is not overly complicated, but I am having a little trouble with it - I haven't been in calc for a year almost, and it seems I have lost my integration abilities with it. Here's the integral: \int \sqrt{1 + (a \pi x^{a-1})^{2} \cos^{2}({\pi x^{a}})} dx I figure the best...

Wow, thanks for the straightforward and informative article!

I also read somewhere that a study linking ELF and RF exposure (long-term, low-intensity, like cell phones) to leukaemia in children was proposed to be caused by the attraction of aerosols by power lines - though I'm sure this (if the aerosol theory is true) has very little if not nothing to do...

Thanks for all the media links - I was particularly lacking those - and for the explanations. This is exactly what I am looking for. I am on a computer without sound at the moment, so I am not really able to examine two of those sources, but I'll get back to you when I do. Meanwhile, I am...

I posted a request for this elsewhere, but I think I'm more likely to get an answer here - by what mechanism might cell phone radiation (low-frequency EMFs) cause tumors? I'm not so worried about the cell phone aspect of it, but it would be nice to know exactly how low-intensity, long-term...

I'm not sure this was posted in the correct forum. Is there anywhere else this should be?

Each of the relationship questions is asking you to compare two variables - disregard any others that are not mentioned in the question. For example: State the relationship between the acceleration and the system mass as a proportionality. The only variables given are mass and...

A week or so ago, my high school physics teacher sent us all summer work - we have to write an article explaining the processes by which electromagnetic fields (particularly low frequency electromagnetic fields) could effect the human body. Since then, I have been wading through the large wealth...
