What is Classes: Definition and 591 Discussions

This is a direct spinoff to the thread I started about which class general relativity is offered in. That question was answered and now I would like to align my math classes to prepare for tensor calculus. Here are the classes I am thinking of taking Linear Algebra Abstract Algebra I and...

I'm a sophomore studying physics and have been doing some academic planning over the break. I'm beginning to realize just how much open space I am going to have in my schedule. My scholarship requires me to take a minimum number of credits each semester, so only taking a few classes isn't an...

I'll be applying for graduate programs in physics and chemical physics in about 2 years, and I want to do research in statistical mechanics, particularly thermodynamics of fluids, non-equilibrium thermodynamics, fluid dynamics, nonlinear dynamics, and other fields related to this. I have time...

Show that if R1 and R2 are equivalence relations on a set X, then R1 is a subset of R2 iff every R2-class is the union of R1 classes. Attempt: I don't understand that if R2 has elements nothing to do with the elements of R1, how can an R2 class be a union of those elements belonging to an R1...

I'm just wondering, but what math classes are the ones that all math majors ought to take?

In the field of computer science, algorithms are often assigned a "complexity" class that is a measure of the time complexity of an algorithm. An algorithm with higher time complexity can take longer to compute than one with less time complexity. I was wondering if circuits also have a...

Hey, I am a math major looking to get my Ph.D. in Nuclear Engineering. Next semester I have to choose between two classes because of scheduling conflict (each class only offers one section; they are 30 minutes apart, but one is at another university which is 30min-1hr drive depending on...

I was just checking out coursera and some others and noticed there many advanced classes available. If completed, how much weight would this carry in an interview or generally on a CV? Would this be considered fluff? Obviously, we are in a transitional period with traditional education...

Homework Statement How many solutions (equivalence classes) are there for the congruence 3x+11=20(mod12) Homework Equations a=b(modn) then for all c, a+c=b+c(modn) ac=bc(modn) ab=ac(modn) then b=c(modn) (if gcd(a,n)=1) b=c(mod(n/d)) if gcd(a,n)=d > 1The Attempt at a Solution...

Hi, I have a (hopefully) quick question about testing out of certain classes in college via proficiency exams. I am currently halfway through my first semester of freshman year and my current math courses are differential geometry and LA. I took a proficiency exam to skip calc 3 and got the...

im currently taking a 1st semester calc based physics class, basically just mechanics i have an upcoming exam next friday, and depending on how well i do, I've considered dropping if i do really bad im a math major at a CC and I've talked to a university representative about withdrawals and...

Homework Statement A solution to a problem has following operation: here, [(a,b)] and [(m,n)] are two equivalence classes. [(a,b)]+[(m,n)]=[(an+bm,bn)] Is not [(a,b)]+[(m,n)]=[(a+m,b+n)]? Can anyone explain it to me? Homework Equations The Attempt at a Solution

I'm trying to decide what math classes to take. I have spoken with some of the physics faculty at my school, and each person has given me differing advice (though there is a general consensus regarding some classes). I am a physics and math major, and am trying to decide which math electives...

Stuck In "Required" Classes I'm a freshman in college right now. I've tested out of MAT 419, PHYS 460, and CHEM 424. I have to take classes such as ENG 101, PHI 101, and ECN 101. What could I possibly do to start working on the Master's level math, physics, and chemistry courses while I...

I may have to get 2Ws in "non-core" classes. I go to a very very small university (small department to the point where some core classes are not offered every year) with a few handful of professors. I am taking a heavy load this term with a full time job. Financially speaking, it is pretty much...

Hello, I am a freshman EE/CompE (Hardware) major seeking a math minor. Since I have already arrived to university with Calc III and ODE's completed, I would still like to dedicate about 4-7 courses of mathematics. I would like some math classes to be applicable to my major as well as others to...

I am kinda anxious about taking upper level physics classes. I want to major in physics and got an A+ and A in physics I and II, respectively, calc-based. I got an A in Multivariable calc and an A+ in Linear Algebra I. But for one reason or another, partially because of all the insanity in...

4 Classes of Math/Physics/Engineering a Quarter -- Too Much? I plan on double majoring in robotics engineering and applied physics at UCSC. This plan mandates an extensive schedule -- four STEM courses a quarter. Is this just a ridiculous load to handle? Or is it, provided the person is...

With this coming semester I have some interesting options for my schedule. The following 3 classes can be interchanged within my schedule: Data Structures - Studies data abstractions (e.g., stacks, queues, lists, trees) and their representation techniques (e.g., linking, arrays). Introduces...

I mainly like physics due to it's applied nature and would like to take two or maybe 3 more course that both teach fundamental physics and delve deeper into mathematics that can be used outside of the immediate field. My choices are: Theorhetical Mechanics Mathematical Physics...

After the basic calc I-III, diff eq, and linear algebra what math classes are most important for Electrical Engineering? I have to take one math elective from this list. Which one will be most useful EE? 3034 - Introduction to Proofs (Limited availability due to course restrictions.) 3214...

Hi everyone, I went to my orientation yesterday. Overall it was very enjoyable. During high school I did both Calculus 1, and Calculus 2. Due to my grade in Calculus 2, my adviser suggested I retake it to keep my GPA as high as possible. She explained that I need to maintain a 3.5 in my...

For the program segment please see attachment. THe program compiles and runs but gives the worng answer; its output is suppose to be like below, if you type in "Our second version of table" on a single line you should get: previous words[i] following...

Is Calc three, physics 2, digital logic and circuit analysis to much just starting at a new school? Any suggestions or comments are appreciated.

I'm still an undergraduate in Physics and decided that Astrophysics is a very interesting possibility to focus on. The bad part is that my school (UIC) does not offer any classes close to Astronomy/Astrophysics other than a 100-level course with the description "Astronomy in the context of the...

I have finished my first year of my undergraduate, taking an Honors BSc in Math with a minor in Physics. I am planning on going to grad school after my undergraduate, and I want to be sure I am not taking too many first year classes. How many first year courses (100 level) courses would you...

Good afternoon everyone, I'll be starting my trek into upper division mathematics next year (applied math major) and since the perquisites are essentially just multivariable calculus and linear differential equations, I can pretty much take them in any order. However, I know that I should...

My plan is to major in Physics and to minor in Computer Science. Here are the classes required for a minor in Computer Science at the college I will be attending: http://www.unf.edu/catalog/link/MINORCCIS3/ Here is a link for course descriptions...

Im taking quite a bit of math this year and would like to know what is learned from these courses .pre calculus is it just alg 2and trig? Physics 1honors would pre calc help me to get a better understanding? College algebra- is it like pre calc (taking it at the community college) AP...

I am majoring in chemistry at UCLA with physical chemistry concentration (transferring as a junior next semester), intent on pursuing research in the field in the future. I would like to minor in mathematics (if a double major is not possible), but I'm having a hard time deciding what classes I...

I've laid out a general plan of studies for my next few semesters here at my community college, and I have already completed the first semester (all 'A's with the exception of Physics in which I received an 'A-'): I had to take into consideration the prerequisites: Linear Algebra - requires...

Good afternoon! I will begin taking upper division mathematics in the fall, and I definitely wish to obtain a Master's right after undergrad, and as for PhD, I'm a bit iffy if I want one (I'll save that for another post in a couple years ^.^) Anyway, I have 4 electives where I get to choose what...

Given the set S, where aSb if and only if a - b \in Z It is asking for the equivalence class and the answer given is S has only one equivalance class for each real number x such that 0 ≤ x < 1. the class [x] is given by {x + k : k \in Z} i dun get it, since S is a set of relation where a...

I have to take any 3 CS electives for my Computational Mathematics major. I'm thinking about Algorithms, AI, and Database Systems. I can take more if I want to. Are there any particularly useful CS classes? I don't really have a career in mind right now.

Hello, does anyone know of any website that has a program that let's me type in all the classes I want to take and type in the times and days for them, and then the program arranges them in ways that don't overlap so I can visually see what classes I will be able to take that semester?

7.5 hrs per week for 5 weeks vs. 3 hours per week for 16 weeks? But during the 16 week class I would be preoccupied with other classes and thus have less time to study... What do you guys think?

Hello, Should I rethink engineering if I am pulling a B in calculus? and My CGPA will be 2.73 at the end of this term. OR Should I repeat some of the classes that I did not do well in?

Homework Statement Solve in K=\mathbb{Z}/_{5}\mathbb{Z}\cdot\mathbb{Z}/_{5}\mathbb{Z} the following system of equations: \begin{cases} 2^{-}x-3^{-}y=1^{-} & 1^{-}x+2^{-}y=2^{-}\end{cases} Not that the ^- means a number with a bar over it. ( I don't know how to input it in the latex software...

Hey everyone, I wasn't exactly sure where to ask this question so I just came here. What is the workload of having AP classes? How much homework will their be per AP course?(I know it's dependent upon the class) I would of asked my teachers, but they tend to stretch the truth. So I...

Hey everyone, I'm currently a freshman in high school taking Biology. For my sophomore year I am enrolled for Pre-AP Chem and Pre-AP Physics. And for my junior year I will probably be taking AP Chem and AP Physics. I'm not really sure what science classes to take after my junior year. Our...

I'm registering for next fall and I am planning on taking: Differential Equations OChem 1 Linear Algebra Statics Chemical Process Princ & Calculations (chem eng) I usually only take 4 classes. Any insight would be great, thanks.

For this summer I have a chance to do a REU at my university that deals with Rubidium vapor. This is a experimental project but I want to go into theoretical physics. However I wouldn't mind doing this because I would learn about atomic physics and it would look good for grad school I believe to...

Hey guys, i am a sophomore (about to be a junior in 1 month), in college majoring in Biomedical engineering and i am planning to take Organic chemistry, multivariable calculus, physics 2 and the labs. Do you think this is too much, my only concern is with organic chemistry. I originally took it...

So I'm finished with all my core requirements, and I want to major in math or physics. I was wondering if grad schools would have a problem with perhaps the following Analysis II (Rudin) Modern Algebra Elementary Topology Differential Geometry (Spivak) My question is, would a grad...

I am debating whether or not I can pull off taking Organic Chemistry II, Multivariable and Engineering Statistics during the 6 week summer term. I need to do this if I want to stay on track with all my other engineering courses. Any advice?

It's my perception from random remarks that have been made here over the years that most people's math/science classes have been populated by a markedly higher proportion of men than women, and that interest in math/science dooms guys to a sort of involuntary monastic existence, as far as...

I'm taking my first two engineering courses in the fall, but I'm thinking I might hold off now until I transfer. I looked up my teachers on rateyourprofessor.com and they both have received pretty abysmal reviews. Is this maybe student's normal reactions to their first engineering courses, or is...

I'm wondering if someone could briefly explain how I can determine the equivalence class of relation? I understand that first you must test the relation to see if is true for the properties, reflexive, symmetric, and transitive. But my main problem is once that is done how can I get the...

(X,\rho) is a pseudometric space Define: x~y if and only if ρ(x,y)=0 (It is shown that x~y is an equivalence relation) Ques: If X^{*} is a set of equivalence classes under this relation, then \rho(x,y) depends only on the equivalence classes of x and y and \rho induces a metric on...
