What is Classes: Definition and 591 Discussions

I have only 1 day to work on my lab. Hope someone could help me as soon as possible. My problem is I don't know how to count how many objects are created in a class. The first assignment is write a Java class, Student, that has the following instance variables: name (String), age (int), gpa...

So it's about time to enroll in classes for the fall semester, and I've finally gotten to the point where I can actually choose my physics classes (instead of falling a specific track of classes). It looks like my choices are: 1) Physical measurements, the advanced laboratory class. I have to...

Hey guys, I'm about to go to college this fall. For my degree, the first math class is Calc 1. I know I'm not ready for it so what classes should I take in the summer? I didn't take a math class my senior year in high school (I didn't take Pre-Calc). So I know I need to catch up. I have 3...

Right now I'm in high school. I want to major in EE and get my BSEE, but I'm not sure what exact classes/minors/concentrations to take to be successful in the workforce. What I really want to do is design circuits for motherboards, cpus, gpus, and basically any microelectronic on a computer, but...

i have talked to at least two people who have said they they have/will retake all the AP/college courses they took in high school at whatever university they are going to. one friend plans on retaking calculus (from 1) because, supposedly, it will be under better teachers. he also says...

Hey guys, I have one more summer left before I graduate with a BSEE. I am about 99.9% certain that I want to go right to graduate school when I graduate. My question is: During the summer, should I take a few electives that I really want to take or should I focus on getting an internship...

hi, i took calc 3 and differential equations. that was about a year ago and i vaguely remember what that's about. I'm thinking about electrical engineering and i heard from many that its math intensive. can someone tell me exactly what math is involved? i've been told to look into classes...

Could anyone help to show that if n is odd then the set of all n-cycles consists of two conjugacy classes of equal size in A_n? Thx

I hope that is the right forum to post to. What follows may seem like it has more to do with economics than engineering but that is not the case: the economics is straightforward but the engineering may not be. In long-range passenger flights there are 3 classes: 1st, business, and economy...

I've been reading ZapperZ's thread "I have so-and-so degree, can I get into Physics?", and I've been thinking what classes I should definitely take so that the qualifier doesn't kick me out of graduate school. I'm in a EE and physics dual degree program, which doesn't require as many physics...

Here is a fun problem, it's hard to write out clearly, but I'll try to do it w/ little confusion. Is it, or is it not true that (2^2^...^2)(n times)=(2^2^...^2)(n-1 times) mod n so for example, when n=2, 2^2=2 -> 4=2 mod 2.

How do you all stay awake through your boring classes? Every year that's my problem. Maybe it's just me but I can't focus too well when I'm falling asleep.:rofl: Is that normal? lol.

It's used to remember the order from brightest (hottest) stars to the dimmest (coldest stars). I remember that it starts with Oh,... then in the middle it maybe be: " Be It A Fine..." Boy/Girl, Kiss Me! So the order is like O ... B G K M It's driving me nuts; please help me!

What are GCE A Levels classes? Can anyone tell me what GCE A Levels are? Thank you.

im a sophomore in high school, and am being offered a good number of ap and dc classes (some of which they have waived prerequisets for so they may be alittle trickey) i plan on taking as many as possible, and I am sure youll get questiones about my homework once in a whie... but, how usefull is...

This is my schedule for my Junior year: American History Honors English III Honors Precalculus Honors Probability and Statistics Yearbook Honors Physics Honors AP Psychology I think I'd like to switch out of Yearbook to take Computer Programming, but I'm not sure if that would make me...

I am considering switching from a chem/physics dual to a physics/math dual, and for the math degree I need to take intro to database systems and computer science 1. Are the computer science classes necessary in a math curriculum? This is insane. Maybe they will waive those classes and let me...

I have not been able to find the quantum constant force problem in the various QM texts that I have checked. I am certain it was not covered in any of the classes I took. Why is that? I would think it would be next thing covered after free particles.

Next semester I need to take Math history and Math for Secondary Teachers, which I think will be quite easy. But I am also looking into taking Advanced Calculus, Modern Algebra, and Mathematical Stats/Prob. As math electives and to get into the MS Pure Math program. Descriptions...

I'm having some problems planning the next few semesters. I'll be taking full loads, 18 units of engineering(EE)/computer science (minor) classes. One thing is bugging me, a comp science class that I don't need for the minor but requires 3 pre-requesites: philosophy: symbolic logic, linear...

So, I'm just picking some classes for next semester. What i have so far: Math 300 - Fundemental Concepts of Math (proofs and stuff mostly it seems) Math 421- Complex variables (basically calc with complex variables..) Physics 181- Mechanics Theater 100- intro to theater Comp Lit...

I just want to make sure that I am doing this right or if I am on the right track. To find a map f :R ---> R so that ker f ={(x,y): x^4=y^4} pi_R: (x,y) ---> {(x,y): x^4=y^4} pi_R: x ---> {R(x): x^4 is an element in X} pi_R: Y ---> {R(y): y^4 is an element in Y} Define f: R x R --->...

I would like to go to medschool. but for now, i am interested in being a math major. Also i need to do some research, not this summer, but the next, which would be after my junior year. I'd like to do research in something computational, but related to biology. What could you tell me about...

Ok guys, what is the difference in going to a city college for summer courses as opposed to the university you currently go to for summer classes (except the $500 difference)? Would grad schools look down on it? Also, do grad schools look well upon students who graduate in say, 3 years or 3...

I'm working on learning how to create classes in C++ and I'm still a little unclear on the syntax for constructor functions and access member functions. We've been using this class called "rational" for working with rational numbers. Header and implementation files are here...

Ugh! I'm working on my last homework assignment and I can't seem to even get off the ground. :cry: The teacher created a class for rational numbers, and now we are working on some functions for a polynomial class which uses arrays of rationals from his class. My polynomials are arrays of...

Hi. Can anyone help me figure out how to find the conjugacy classes for a certain group and the elements in each class. I'm looking at the dihedral group of degree 5 (D5). I found the 10 elements in the group, but I don't know how to get the conjugacy classes and the elements in them? Can anyone...

This is getting crazy. I'm online now because my English class was cancelled, yesterday we had Physics for the first time in over a week. My Drawing class was canceled yesterday. And then two weeks ago Calculus and Speech were both cancelled. It is really annoying. :grumpy: On the other...

Hi, I am currently majoring in physics, this is not the problem! The problem is my option classes. I am finding that my option classes are bringing down my GPA, ie English, Sociology, ect. (Honestly what the hell is the point of studying poetry? )It just seems that no matter how hard I try...

next year, my school is going to be offereing 200+ AP classes (im a high school sophmore) . I am taking calculus right now but my school doesn't have any science classes so i was planning on taking AP physics next year. any advice? thanks.

I was wondering if I should take easy professors for my math and physics classes? I am about to register for spring and I found an easy teacher for vector calculus. I am tired of having the hard profs..I mean I know regardless of how hard my teacher is, I am going to work to my full potential in...

Hopefully this sort of questions will soon be answered in the tutorial (good effort, Dduardo!), but for the time being, this one is not. I have the following scheme: class Foo { ... protected: struct PartOne { ... }; struct PartTwo { ... PartOne* someFunction (); };}...

Hi I just wanted to know what a qoutient space is . Is there a physical picture to it? How can one imagine what an equivalence class,equivalence relation is?

I'm a freshman mathematics major (I've heard that you don't officially have a major until your Junior year, but that's what it will be). I go to a local community college and I'll be transferring to a regular university after my sophomore year. I know that different programs will have...

My school teaches differential equations and linear algebra at the same time. And this upcoming semester is my favorite professors last semester teaching it for a pretty good while. Do you guys think it is worth taking three math classes (calc3, de, la) at a time to have a good professor...

From what I collect the biggest waste of time are these secondary classes that demand busy work which pushes the time spent towards the classes one cares for into the gutters... I wonder why school systems enforce everyone to take core classes and these required classes that are blatant waste...

What software do you recommend to try to learn.. maybe take some classes related to 3d engineering.. not just mechanical but also structural.. etc

Questions about functions: Let A be a set and let f: A -> A be a function. For x,y belongs to A, define x ~ y if f(x) = f(y): a. Prove that ~ is an equivalence relation on A. This is my guess, but I am not sure whether I'm right: Proving reflexiveness: If (x,y) belong to A, then f(x)...

I am being asked to discuss antibiotic resistance for a take-home exam and I was wondering if I am missing any classes of antibiotics. This is what I have: *Sulfonamides *Quinolones *Penicillins *Cephalosporins *Tetracyclines *Aminoglycosides *Macrolides *Chloramphenicol *The book...

I'm interested in how different systems from different countries "teach their young". I noticed in the College Help area some problems I was doing in my 10th grade and not because I was a genious, but because teachers asked me to. I was surprised. I was expecting questions from QM at least. So...

First of all, I recently purchased a Calculus book for a real bargain: $ 0.75 + tax! I spent spring break giving myself a refresher course. Whee! On to business: I think Calculus classes deserve special mention. They are among the very rare classes where cheat sheets are not only permitted...
