1. ### Schools Do most schools require a science other than Physics for Physics majors?

My community college, like the major in-state (Idaho) universities, requires two semesters of General Chemistry from all Physics majors. I'm pretty sure most schools I've looked at have required 1-2 semesters of it. If you can avoid it, do so imho; they're rather common weeder courses, and can...
2. ### Confusion about squeeze theorem example; plugging 0 into x when x ≠ 0.

I more than readily admit that some aspects of limits escape me -- I can solve them but my intuitive grasp of them is rusty at best. Where I initially became confused was from seeing "Since limx →0 (1 - (x2/4) = 1". I look at that and think "Hey! They put in 0!" I'll take a look at that...
3. ### Confusion about squeeze theorem example; plugging 0 into x when x ≠ 0.

@Don: I'm assuming that the only way 1-(x^2/4) can be equal to 1 is if you assume x=0. I'm also assuming that you have to make x=0 for 1+(x^2/2) equal to 1. Like I said I'm probably grossly misunderstanding some part of this, which is why I'm asking the question. xD From my novice point of view...
4. ### Confusion about squeeze theorem example; plugging 0 into x when x ≠ 0.

This is from a textbook but it is not a homework problem, it's an example following the introduction of the "Sandwich Theorem". It says "for all x ≠ 0", but then it appears to assume that x = 0 when it finds the limits of g(x) and h(x). Clearly 1 ≤ u(x) ≤ 1 means u(x) = 1, I don't dispute...
5. ### Programs Would I do well in physics majors?

Not if those study habits don't change. High school grades really don't matter once you're in college, so long as you turn things around and start earning higher marks. You'll be retaking physics, and likely starting at the bottom of the calculus ladder (or lower, depending on how you test on...
6. ### This might be a silly question but

It really depends on your school. In the USA, there are a lot of required courses that don't have anything to do with your major. At my CC they require 6 Arts/Humanities, 3 Communication, 6 English, 2 PE, 6 Social Science, 3 Social Sciance/Arts/Humanities (26 credits) in addition to the 38...
7. ### Programs Reviewing elementary mathematics for physics major

Well there are the usual suggestions (textbooks, subject-based help books like X for Dummies, Khan Academy, etc) but I've been reviewing using Screencast videos posted by my College Algebra/Trig professor. The Math 147 videos represent an entire semester of PreCalculus classes; 1 50~ minute...
8. ### Reading Mathematical Theorems And Their Proofs

I'm only just entering the calculus sequence, but as I understand it a solid understanding of proofs is necessary for later courses. Depending on how 'theoretical' your future calculus courses are you might encounter them there, but you'll see them in Linear Algebra and if you take any Analysis...
9. ### Is it normal to forget most previously learned material?

That's sort of our point. Perhaps I'm misunderstanding your argument(s), but from where I'm sitting it seems as if you're... well, perhaps not arguing in favor of poor study habits in general but at the very least defending your study habits specifically. I don't mean to suggest that you have to...
10. ### Is it normal to forget most previously learned material?

I don't mean to imply that you're struggling, only that in time you will with your attitude. In a previous thread (March 15) you spoke of burnout, of switching subjects after 10 minutes and of being in Physics I/Chem I, meaning you have another semester of Physics, another semester of general...
11. ### Is it normal to forget most previously learned material?

Woopy, I took a look at some of your other posts. You're clearly having a hard time picking a major and further you state that you never really had an interest in medicine, you're bored in your math/physics classes and with the finer details of biology. You prefer the macroscopic to the...
12. ### How do you know if you're ready for the test? (physics)

Problems. Lots and lots of problems. It's a bit like the early Trig proofs, the more you do the more tricks you learn.. so while there are a near-infinite amount of ways to rewrite and over-complicate a simple identity to see if you can prove that it is in fact an identity, the more you do the...
13. ### Post Your Summer/Fall 2012 Class Schedules

Summer Courses: Calc I PE (Required credit.) Some random "cultural diversity" internet class. (Required credit.) Schedule-permitting I'll be working through Linear Algebra by Friedberg/Insel/Spence and trying my hand at Spivak to get a head start on the Fall. Not sure how that's going to...
14. ### Need help setting up next semester

Assuming your school is like most, each Associates degree has a specific set of required courses. At mine, an AS (and that's what you'd probably be getting) is 64 credits. 6 English, 3 Comm, 3-5 Math, 8 Lab, 2 PE, 15 Liberal Arts. Even if you have all of those done, you're not yet ready to...
15. ### Need help setting up next semester

I needed a bit of history so I checked some of your other posts. It seems you've been in school for 2~ years now and you said you just finished trig, so I'm assuming you've also completed college algebra. If that's the case, and if your skills are up to the challenge, there's really no reason...
