I know what dx is, but I didn't really express my question in the best way. If you like though, in terms of integrals, dx is the infinitesimal parts that the area of a curve is split up into. The thing is, du isn't just equal to dx. I mean it represents something else, in this case cos(x)...

Hi, We were going over trigonometric integration in Calculus II the other day. I got the basic idea, but get lost when we're doing the u-substitution. We had a problem like this: \int cos^3 (x) dx Then we did: \int (1 - sin^2 (x)) cos(x) dx Starting u-substitution: u =...

Your math looks good, but you made an error in your calculation. I'm getting 116/3.

Thank you very much! I really like UIUC, from what I've read about it so far. They seem to have a very good disability services, too. I also like Purdue. I will definitely check out UCSB. Right now, UIUC and Purdue are at the top of my list for the schools I have a better chance at. Which...

All right. I need suggestions though. Honestly, I hadn't heard of Rutgers or Stony Brook before today. I know of Penn State, but they have the reputation of being a party school. That's why I don't care for them. I'm open to suggestions, though. Also, how do those compare to Purdue? It...

Actually, I hardly knew of any good universities for physics, except for MIT. What I found was through looking up rankings for various universities for physics. That was my only resource. I also asked here, in order to add to that list. Did I say it meant anything? I just said I hadn't heard...

I don't understand. I'm already paying that much, so will be paying that if I transfer or not. I just want to be in a better physics program. The only way I can pay much less is if I go to Penn State, and I don't really like it there. How couldn't I afford to do research? Yes, it'd be...

Yes, that's exactly what I am thinking. Interesting. What specifically would you recommend? I have never heard of Rutgers or Stony Brook. I'm not sure about Penn State. When I looked into it before, it seemed not to be that selective. I mean that I want something challenging; not...

I'm well aware. I've worked hard to keep the grades I have in college right now. I know it won't be easy. My main concern right now though is geting in somewhere. So, any suggestions?

True, but surely one who has both gone to a good university and done a lot of research is better than both of these? I just feel like I'd have more and better opportunities at a better university.

Yeah, I understand that, but I want to go to a university that is known for having a good physics program, so that it stands for something when I go to apply to grad school.

Sorry to double post, but I have some updates and clarifications. I looked at the costs for various universities today, as well as their selectiveness. I'm really liking Cornell. Their selectiveness seems to be comparable to CMU, and they are even a little cheaper. I was mistaken about...

I agree. Algebra II is vitally important in any and all math you will take in the future. Trig can help, too, but you can learn that anytime, and it is really easy, anyway. I never took a precalculus class, so I don't know what is involved. My Calculus I class covered anything I needed to...

Really? I didn't think it was all that much for a private university. Everything I looked at seems to be in the $40,000 range. Why do you say it doesn't matter? Yeah, CMU seems pretty good. I think I'd have a good chance at getting in there, especially since they said that they give more...

Hi, I'm going into my sophomore year at Duquesne University, majoring in physics and math. I am thinking of transferring to another university, however. The reason is that I really want to be able to get into a top grad school to earn my PhD, because I want to go into research. Duquesne's...
