In summary: I don't know what to do to speed it up.In summary, Kramer recommends that the person struggling with the epsilon delta proof start with the easiest examples and work their way up. He also recommends that the person seek out tutoring or a math center.

I'm getting bombarded with trying to understand the epsilon delta proof. I'm also getting killed in fields and proving things in that class. The only ones i feel like i have any chance are my computer science classes and discrete math class. What do you guys recommend me? I'm not particulalrily intelligent. But i'll work at it. I just don't really feel like i know where to start.

I remember the good old days with just doing straight up computations. But gone are those days. Now it's about proofs which i definitely respect and want to understand.

For most people it works better to do examples than to sit around thinking. WRT to epsilon delta try to see if you can do the easiest examples:

limx->ax = a

limx->acx = ca

limx->ax + 5 = a +5

limx->ax^2 = a^2

if limx->af(x) = 1 then limx->axf(x) = a

if limx->af(x) = c then limx->axf(x) = ca

etc

One thing that trips people up with epsilon delta is that the goal is not to "find delta." There is no particular delta to find.

Studying proofs is a lot different from computations. My advice, use your book and study the proofs very slowly and thoroughly. For the first class I took in analysis for my math degree I remember being amazed at how tiny the book was. All the language is incredibly concise, and I could easily spend hours trying to understand a single page. It's a different skill you have to learn that you generally aren't taught in high school or in other college classes, so put the time into let it develop. It's more philosophical than the computational math you're probably used to, so don't feel like you're wasting time by just carefully thinking about the problem without writing anything down. Hope that helps.

From my experience, many math professors also don't know how to teach these subjects. They teach by rote memorization without explaining why method A is a good method. You might try finding a tutor if your school has a math center, and see if they can explain it in alternate ways.

I was having the same concern last week on the epsilon/ delta proof (I would say my whole class was after reading the class posts). I found the Kahn Academy videos more helpful than my Professors on-line power-point slides. I also watched several other you tube videos on the subject, and at least now I feel like I'm starting to "get it."

What class is this, Calc 1? From what I remember, only about 5% of the class really understands the epsilon/delta proof when they heard it in Calc 1, and most of the class could not repeat the definition of the derivative at the end of the semester. I agree with jrjack. Unfortunately, a lot of math teachers just teach you how to solve problems without really understanding what you're doing, this has people lost when they get to Calculus and are asked to digest some real theory.

Kramer can confirm, but since he mentioned taking abstract algebra ('fields') in the OP, I'm assuming he's already completed Calc I. Maybe this is an introduction to analysis course?

In any case, I think some tutoring is probably the best place to start. As another member mentioned, see if your university has a tutoring/math center.

These proofs should be in your textbook. Don't expect to "see" the whole proof in one go - you only need to understand each step of the proof. Once you understand each step, and can reproduce them in the exam, then you are there! So on which step do you get stuck?

I assume the OP is not in the US based on his subjects.

Actually this is the first course on algebra for math students. Same with the calculus course. It's directed towards math students. My teacher wanted to start us up on the idea of fields. I'm finding math to be fun but it's just that it takes me literlaly 12+ hours to do 1 question from the assignment. It gets annoying too. More frustrating than anything. I've been going to the tutoring sessions and TA office hours for the past 3 days now. It's definitely helpful. I guess i just got to suck it up.

Also I'm from Canada.

I know it's tough, but I think you have a good attitude. Knowing when to suck it up, and find your low gears, separates those who finish from those who don't. Best of luck to you!

It seems like you've hit a brick wall. Trust me, it happens to everybody in math, even to the greatest. You need to persist through this, because if you do, then a time will come that everything clicks and you will find things soo easy and fun!

That said, spending 12+ hours on 1 question definitely is too much. If you spend 1 hour on it, then I suggest that you post the question here on our homework forums so we can help you out. As long as you're willing to think about it, you should be alright.

if you can fathom post #62 of "who wants to be a mathematician?" you can handle any pure math course. perhaps even if you can't. don't give up too soon.

My first theory-ish class I was struggling with so much and I didn't know where or how to start. My professor was vague and I couldn't synchronize with the textbook's reasoning. I decided to get a tutor and everything became so much easier. Something to consider.

Kramer733,

Consider taking a course in symbolic logic. You might be able to take it from the philosophy department and get credit for it as one of your non-math requirements. It can clarify the "game" of doing proofs.

Well that's 12 hours of fun :) This isn't school. Many University assignments demand that amount of effort... get used to it...

This is precisely what I'm doing this semester. It's really helped me learn the proof-construction process as well as how to approach a problem involving proofs.

What is the reason for struggling in math after only 3 weeks?

There could be a few reasons for this, such as not understanding the material, not having a strong foundation in math, or not having enough practice or studying time.

How can I improve my math skills in a short amount of time?

The best way to improve is to practice consistently and seek help from a tutor or teacher if needed. You can also try studying in a different way or using online resources to supplement your learning.

What should I do if I feel overwhelmed with the math material?

Take a break and come back to it later. Make sure to stay organized and break down the material into smaller, more manageable chunks. Seek help from your teacher or a tutor if needed.

Is it normal to struggle in math?

Yes, it is completely normal to struggle in math at times. It is a complex subject and it takes time and effort to understand and master it.

What can I do to stay motivated in my math studies?

Set achievable goals for yourself and celebrate small successes. Find ways to make math more interesting and relevant to your life. Surround yourself with supportive peers and seek help when needed.
