Can somebody explain to me why I need to take a Complex Analysis class?

I'm doing a MS Mathematics and going on to a PhD in Statistics/Probability

I don't see any fucking point in studying Complex Anal.

Are you sure you have to take that specific class? At my university there are distribution requirements, where you might have to take a year of some type of analysis class. Maybe you can change the MS program you are enrolled in to an applied math MS where the requirements are different. Even then, complex analysis is a branch of math that has a lot of real world uses, it's not like this is a class on Galois theory.

Here you are required to take 2 semesters of regular analysis, but not the complex.

complex analysis is useful for a lot of things in math. Since your ms is in math and not statistics, complex analysis is considered an essential core course, like abstract algebra or real analysis. With your PhD studies in mind, complex analysis can be useful because it gives a way to evaluate a lot of different definite integrals over the entire real line. Even for real-valued functions, we can sometimes solve otherwise impossible integrals by passing to the complex plane, taking a clever contour, and then taking the limit as the contour expands. This comes up when you are trying to find the fourier transform of certain functions, for example, or when you want to integrate certain PDFs over the entire real line. It's a useful class anon. Even if it doesn't seem like it. Lots of great statisticians were at least proficient in complex analysis.

Haha Then why are you studying math? You could say the same about most math subjects. I've had complex analysis twice already once for bachelors and once for masters. It is used throughout many other fields of math and used gratuitously by physicists.

So i've got a question regarding university level math. I'd like to start studying Business Informatics. I'm currently working as a developer at a bank, so that's probably an advantage.
My problem is that I basically dropped learning mathematics when we started with functions like f(x)=12x²+4x³+23 and stuff like that. It's not that I'm not good, I had a few bad teachers and even more personal problems. Now i want to gitgud again.

So what resources should I consider? I'd like to get a some good recommendation regarding university-level mathematics that start small but go big.

The fact that the equation is using the variables "a, b, c, and d" and it that they are equal to zero implies that this is a 3D plane equation. Like other people have pointed out, there are infinitely many points that would satisfy this equation in Euclidean space because geometrically speaking you can place an infinite number of points on any given plane.

Hi guys,

Wondering if anyone could point me to an introductory level book on Math that teaches primarily by showing how to visualise the math so that I can understand HOW it works (as opposed to just memorising the equations/procedures and accepting that they work).

I'm thinking of going Feynman's Lectures atm, but am wondering if there's something better you guys might recommend.

Again, would like it to start at the very basics if possible.

Thanks and Jesus.

I am taking a class in abstract algebra and was getting ready for a test and noticed a pattern that has popped up when shows how to represent all polynomial functions in a ring that map from Zmodn to Zmodn. What I (think) I found is pretty much why when you have some value x^n it can be replaced with x etc. Pretty much showing why there is only one way to represent all the functions withing the ring due to not being able to have any x raised to something larger than n-1

As somebody who dropped out of studying math after 3 months, don't sweat it.

That said high school math is very different to academic math. You won't be learning calculus or algebra, at least not at the uni.
However you learn about proofs, what you need them for different kinds of proofs and how they are done. You'll need some algebra to follow the exercises and examples, but nothing really substantial.
But you might discover that Math in it's academic form is an ivory tower and if you want to do anything but being a researcher you'd have to find your own interests to do something financially worthwhile in life, which will be if you really like math seem stale in comparison.

If you want to learn something exciting that relates to the real world get out asap.

An undergraduate degree in math almost always requires taking a sequence of calculus classes that lead in to proof based math. There are many people that get undergraduate degrees in mathematics that go on to work in the private sector successfully. It is inaccurate to say it's in ivory tower field, that is only accurate if you want to become a professional math researcher, which even a large portion of those with math doctorates don't pursue after their thesis.

OP if you're interested in math stick with it. There are jobs out there for people with math aptitude. You will probably have to learn how to program.

Math related jobs are high satisfaction because they generally pay decently and the process of learning various fields of mathematics can be really mentally rewarding depending on your personality.

On the other hand, if you want a more streamlined career progression that follows a pipeline you may want to choose a more professional style of program. If you study math and don't want to become the ivory tower researcher, at some point there is a transition you have to make in to doing real world things that causes even the most intelligent people to "fall off the wagon" sometimes.

I am certain i am missing information so i appeal to you brainy smarties to educate me However this also may be a physics questions. I dunno.

Do curves actually exist? Meaning at the smallest point possible (I would assume planck length) would it not be a straight line from point A to point B then a second straight line from point B to point C etc etc? Only upon pulling back far enough to no longer see the individual points does the curve appear?

Any model of reality discussed in language is "sort of" discrete because language is a discrete medium. However, to the extent that language can describe the idea of continuity at all, it can also encode it in a model of reality, so there is no comprehensible sort of continuousness which cannot also be a property of the Universe. As such it makes no sense to argue that the Universe is discrete because the models are discrete, because "the models are discrete" is not a meaningful statement: all possible models are discrete because the means of communicating them is discrete. Effectively the argument becomes that no continuous universe could contain beings which communicate about said universe in a discrete language, which is clearly silly.

I personally think the study of differential equations is more important to have down before the linear algebra when learning the basics of QM, because then you can get a feel for what Shrodinger's equation is saying, but there is much debate on the proper pedagogy for teaching it. Vibrations and Waves by French is my personal choice for learning diff eq.s and linear algebra/ their applications to physics all in one nice bundle. Also Mathematical Methods in the Physical Sciences by Boas has been a life saver for soooo many areas in physics. I still keep my copy of it from sophomore year in college on my bookshelf.

Learn calculus, differential equations, linear algebra, and abstract algebra/group theory. Read Quantum Mechanics by Shankar. When they start about euler lagrange equations as a way of doing classical mechanics problems check out Give Taylor's Classical Mechanics.

If you want to go deep the Landau Lifshitz books are essential. Griffith has a good E&M book if you are only interested in learning enough E&M to do advanced quantum. Gordon Baymn's lectures on quantum are really dense, but really well summarize the most essential aspects of quantum, and teach you how to solve some really practical problems (spectroscopy/scatter/super conductivity class shit). Messiah's and Sakurai's textbooks are each good in their own ways.

You need calc 1 and maybe calc 2 (techniques of integration) for undergrad level physics books (specifically Newtonian mechanics and Electromagnetism). I used University Physics which you mention and Fundementals of Physics by Halliday and Resnick, either will do (get an old edition for cheap) but I personally liked University Physics more.

As for QM you'll need linear algebra and differential equations, both of which you should study after calculus. I'd recommend getting an old edition of Calculus by Stewart, Spivak might be too much if you've never seen calculus or if your algebra and trig is weak. Undergrad math textbooks are generally shitty money grabs, and MIT has some of their's up for free.

For other book suggestions I'd recommend looking at a university's physics courses and their respective syllabi.

Everyday before work, I woke up 2 hours early and forced myself to read/do exercises of the following books. (this later became 3 hours). I averaged 3 books per month if they were survey books, and about 1-3 months for a rigorous book. This became an easy routine after the first week, and I'm still doing this.

>1) Daily Rituals by Mason Currey
https://books.google.ca/books/about/Daily_Rituals.html?id=hA-MoAEACAAJ
This is where I got the idea of making a routine from, it's a survey of historical artists, philosophers, scientists ect who all had a routine in order to get work done consistently. Franz Kafka would split his sleep up into 2 section in order to fit in work beside his regular office job.

>2) Basic College Mathematics by M. Lial et all
https://books.google.ca/books?id=ucUDMAEACAAJ&dq=basic+college+mathematics
As mentioned before in here this covers elementary school and Jr. High math basically. You can just survey this for the most part (not do any exercises) unless you don't understand something, then do the exercises. Took 3 days to survey this. When I later took Harvard's CS50 computer science course, the first lecture about Binary numbers directly was related to this book's first chapter on whole numbers. I torrented this book.

>3)Basic Mathematics by Serge Lang
https://books.google.ca/books?id=gBtvo480ng4C&dq=basic+mathematics
I got out the notepaper and did most of the exercises by hand. This was all focused on reasoning, why is this true, how do we prove this is true, ect. This book teaches you so well that applied calculus is your bitch afterwards. I torrented this book too since author dead, copies are like $80 on amazon.

>That's a slow pace,
Yes, I know it. That's because I got my bachelor degree in maths but never studied it seriously until now, that I have noticed my lack of foundations; and it's because of that that I don't go on unless I'm pretty sure I have solved and understood every single part of the text and the problems, specially set theory and logic, wich are basic for all mathematics. Solving all the doubts arising when studying mathematics is a very important part of our study routine if one really wants to understand them... and it's probably the most tedious part.

>Shoenield's mathematical logic
I'd swear it was a model theory book. I remember I didn't buy it due to that, and bought Richard E. Hodel's An Introduction to Mathematical Logic instead.
