Expand[(1+x+x^2+x^3)*(1+x+x^2+x^3+x^4)]

What if you grab a book like "Fundamentals of Physics" by Halliday, pick out the chapters that interest you and read through them, it's a textbook but it has pretty long explanations and the math involved is straight forward. Or maybe if you just just want a general idea of concepts you...

Gauss's law finds the charge ENCLOSED, So one way to do this question is to enclose the charge by surrounding the charge by another 7 boxes. Then you can compute the integral as the charge is now enclosed. There will be 24 faces after surrounding the charge, so integral will produce a flux...

Do you mean that it should be shown what the is? z= y-1x y ?

Thanks for replying Hurkyl So it would be a similar argument just clarifying that the for some (not all) x,y in G? For some x, y in a non-abelian group G xy≠yx and if xy = yz for some z in G then x≠z otherwise xy≠yx Is not satisfied for elements x and y of the group

To show that a non-abelian group G, has elements x,y,z such that xy = yz where y≠z, Is it enough to simply state for non-abelian groups xy≠yx so if you have xy=yz then it is not possible for x=z due to xy≠yx? Or is more detail required?

Hey, Chemical engineering would be pretty heavy on math and physics, however if you actually want to do this you motivate yourself to do well once your in university. When I started my physics degree I felt like I was terrible at both math and physics, many assignments later I began to...

Yea you definitely HAVE to take linear algebra, I took Calc III at the same time as an electro dynamics course and they both ran really well together so you should probably consider taking that class as well,

Wow, This is really cool. Thanks Borek

Very good book on group theory with a lot of examples. http://web.science.mq.edu.au/~chris/groups/

Yea I agree, Industrial engineering would consist of less computer based classes and my physical engineering kind of classes. At my uni they are under the same degree outline but have almost completely different streams. There are a few overlapping classes such as math, physics and...

It might be pretty difficult to find someone to take you on, I had a summer scholarship at my uni which just ended a few weeks ago and it required at least 3rd year undergraduate knowledge, and 60% of the time I was reading and learning about new things to progress with work. You could always...

Hey, I'm studying physics and mathematics at mq in Sydney, Halliday, Resnick, Walker: Fundamentals of Physics Is a really good book, if you sit down and read it from the beginning you might be able to get through the first few chapters which are pretty much high school physics anyway...

I think it can be all the reals except zero, but the fact that both t's are to the power of two cancels any negatives. So you would really just end up with all the positive reals as any negatives would produce the same solution as positives.

Hey, I've been trying to solve this question, Show that <a in D8 : a2=1> is a not a group. I might not be processing it properly, but my interpretation of the question is that <a in D8 : a2=1> = <(a,b): a2=e, b2=2, ab=a-1b> Which is just D4, a group, the set of dihedral where...
