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...
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...
@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...
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...
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...
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...
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...
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...
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...
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...
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...
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...
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...
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...
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...
In my experience it's definitely the work you put into it. I started my college journey in Beginning Algebra (Sad, right?) and moved onto Intermediate Algebra before even getting into College Algebra. I had Bs and Cs in all of those classes, not because they were too hard but because a) I wasn't...
I'm not expert, but.. computer programming isn't a degree. It's not even a field, it's more of a skill. There's nothing to stop you from developing that skill while taking another major. I say this because you didn't say "I love computer science.", "I love data structures." or "I love compiler...
I'm not, no. That doesn't mean they don't exist, just that I'm not aware of them. Most schools evaluate transfer credits on a case-by-case basis, deciding whether or not to accept the credit or require you to take retake courses. It is incredibly important to speak to admins at the school you...
I think the idea of a 'true' interest is.. eh. Flawed. It's a bit like the idea of a soulmate. As I see it, we each have some broad spectrum of potential interests/people out there and which one we end up spending the most time on/with is largely due to chance and circumstance. You happened to...
Yeah I reworded that last bit when I realized that I was asking about the rules governing manipulation of complex numbers (which I've covered before in previous courses) instead of the method of treating complex numbers as coordinates rather than a+bi. I'd never seen 'i' treated in that fashion...
Aheh, this answer is closer to what I was looking for, although I suspect I should've asked this question on a programming forum rather than a mathematics subforum! Since asking this question I indeed have wondered how the calculator represents real numbers, although I have a conceptual grasp of...
At risk of butting into a conversation not my own just to satisfy my own curiosity.. wouldn't the above statement be true for ALL triangles existing on a sphere? Including the "infinitesimally small triangle" that DaveC~ mentioned on the 'outside' of your 900~ degree triangle. On an infinite...
Ahhhh you're right. :blushing: When I took the natural log I removed the e and left the ln; I forgot to mentally remove the ln after I applied one of the log properties. Fail.
Ah see, I didn't know that. ;)
I suppose I'll have to wait for Calc II then. Hell the whole idea of a complex...
@Micromass: Just to be clear I'm not at ALL saying the mainstream is wrong and I'm right. I recognize that I'm wrong and that the way I'm seeing it is incorrect, so I was hoping to have my view corrected. ;) But to elaborate on my confusion, to get from 23.1~ to -1, something is being done...
Like many math newbies, complex numbers (or at least the idea of complex numbers) are a source of some confusion... but I've worked with them before and I'm reading through posts on PF that I hope will give me some sense of intuition about them. That said, there is one nagging question that I've...
Thanks for the insight. ;) I'm aware of the connection between WSU and UI, I always figured it was to make up for shortcomings in the UI physics department; I know UI has had some funding issues in the past, even going so far as to consider dropping their undergrad physics program altogether. Do...
(Longish reply.)
I'll second Quark's answer. I attended an "alternative" high school where students were essentially funneled away from academics and towards trades... plumbing, construction, welding, etc. The highest math class was Algebra (which I got a C in), there was almost no...
I'm a little worried about this myself. The only Calc II class I could schedule in is rumored to be... well. Difficult. By that I mean the professor is described as "brilliant", but his tests are "handwritten mind games". My brother took this prof for College Algebra with 35 other students and...
Well I can't edit my post and no one seems interested in answering, so I'll rewrite my question. I went through the pages course by course and tried to figure out which courses were equivalent.. I came up with these differences:
UI: 2 Semesters Analytical Mechanics
ISU: 1 Semester...
-Learn to program. Take a few select CS classes if you can, but it's not required. Hell, I hated my CS class most of the time and dropped it towards the end of the semester. The professor kept pounding "Computer Science is not programming!" into our heads and he was right. I rather liked...
