Almost half of it's content is online? And expensive? Are you kidding me? http://www.amazon.com/dp/1133110878/?tag=pfamazon01-20 Anyway I'm considering an advanced course in linear algebra, and after researching the library and online reviews I found these 3 texts to be the most famous...

Which universities or instructors---anywhere in the world and particularly in the USA, Canada, UK, Australia, New Zealand, or India---use or have used Tom M. Apostol's landmark textbook on Mathematical Analysis? Are there any video lectures from a course based on the text available on the...

In the past few weeks, I have occasional trouble with my latex expressions (using the itex tag) running over the text that follows them. I also see this in some posts by others. Is there a good way to avoid this? Is it a browser specific problem? ( Mozilla and Firefox are mine.)

Hola While searching the textbook stores online I noticed that Academic math books are generally super expensive, ranging price from $150 to $300. Some texts are a few hundreds, 300 pages and they cost up to $200 or more? Come one? Please don't tell me because they have the hardcover or...

It has been awhile since I've posted. :rolleyes: Anyways... I'd like to start learning multivariate calculus along with linear algebra. However, I have a little problem in choosing a suitable text. I'd like to have a text with more theory and less applications. Some people have recommend...

Hey there people, I've got a fascination with the sciences, especially Physics. In a year or two I'll have the time to possibly study it at Uni. Most likely entering as a mature student. Anyways, I plan on using this time up until then on getting my Maths up to scratch. The last time i...

As per the title, I need a cryptography book that does not shy away from math. To me it seems like many crypto books are scared of presenting the theory from a mathematician's perspective. I was recommended Cryptography : Theory and Practice by Stinson, can anyone comment on it? Any help is...

Hello. I am currently taking Physical Optics and I do not particular like the textbook I am using and was wondering if anyone had any recommendations on study tools (books or websites) to help me with what we are learning. The class is of the undergraduate level, and the book we are using...

Hello! I have a file that looks like this: Where every line beginning with a T is a new data set. So basically I need each line in the file to look like this: I need to merge every other line so that each data set lies on the same line. There can just be a space in between the two...

I am trying to read and display the content of a text file in Fotran 90 to make sure that fortran is interpreting the data correctly. Eventually I want to store the data in an array so I can calculate averages, but at the moment I am still working on getting the data displayed in Fortran. I've...

There is a proof offered in the text "Theory of Functions of a Complex Variable" by Markushevich that I have a question about. Some of the definitions are a bit esoteric since it is an older book. Here "domain" is an open connected set (in \mathbb{C}, in this case.) The proof that...

I'm taking multi-var calculus next semester and I found out that we are using this terrible excuse for a book: https://www.amazon.com/dp/0470131586/?tag=pfamazon01-20 Anyway, I have been studying ahead using my huge copy of Stuart, which my university uses for Calc I and II. I asked my...

In his "an introduction to quantum field theory", problem 5.4 (c), he describes a bound state of positronium as |B(k)\rangle=\sqrt{2M}\int{\frac{d^{3}p}{(2\pi)^{3}}\psi_{i}(p)a^{\dagger}_{p+\frac{k}{2}}\Sigma^{i}b^{\dagger}_{-p+\frac{k}{2}}|0\rangle} where \psi_{i}(p) are the p-orbtal...

Hello, Does anyone know of a REALLY good tensor analysis text. I am a chemical engineer who is working on a masters in EE and would like a text that covers fluids applications as well as rank 3 EE applications and even some rank 4 general relativity would be nice to see. It would also be...

...or more likely, I'm just being retarded. So here's the offending statement: Let X be our random variable with a countable range of {x_1, x_2, ... , x_n, ...}. Let f(x) be a discrete density function and F(x) the corresponding cumulative distribution function. Then, f(x_j) = F(x_j) -...

Hello! I just finished my undergraduate quantum mechanics education and am looking to self-study the next level some time soon (after finals!). We used Gasiorowicz in my class: a god-awful pedagogical text in my opinion. Though I've done pretty well in my course (I'm fairly certain I have...

Critique this linear algebra text Micromass has said before that there are a bunch of bad linear algebra textbooks out there. So someone linked me before to a free linear algebra text and I wanted to ask the forum community's opinion of it. http://joshua.smcvt.edu/linearalgebra/book.pdf...

Dear Fellow Members, I am presently trying to write a Fortran 95 program to separate acids from a list of chemicals in a text file and then write them to a second text file. The program first matches the word "acid" and is then supposed to check if the word preceding the word...

Hi everybody, I have 3 columns of data (3 different variables) and 400 rows. How would I set up a matrix/array sort of thing to read each row individually and store it in my fortran program to calculate equations at each step? What I have basically tried and can't get to work, I think it...

I am in my final year of a physics degree and have taken all the undergraduate mechanics available in the department, but I don't have a really solid understanding of Lagrangian and Hamiltonian dynamics. Does anyone have a recommendation for a mechanics book which is comprehensible for...

Hey, I was wondering if anyone could suggest a good linear algebra text that gives thorough coverage of vector spaces over all sorts of fields. It's difficult to find a book that doesn't focus pretty much solely on real and complex vector spaces that isn't at too high of a level. (Although I...

I've been using Latex for many years now. But there is a feature which I feel more and more uneasy about: At least in plain latex you are supposed to do subscripts, minus signs, in math mode, even when writing a simple number with exponent in text mode. Another example would be expressions like...

Alright, so my girlfriend and I are planning to go to the Renaissance Fair tomorrow morning. I'd leave my house around 8:30 and pick her up at 9. She offered to cook me breakfast tomorrow morning before we leave, but I declined, since I'd already be waking up at 8am as it is, and I don't want to...

I'm looking for a text with loads of worked examples , plenty of exercises, and since I'm working alone , a solutions manual - or some access to the answers - is vital. Currently working Griffiths. The only way to master this demon is by doing dozens of problems. Any suggestions appreciated...

What is a good, solid reference text for multivariable calculus? Ideally something you'd get by following on from Spivak's Calculus into 2/3d/Vectors etc. I've already done the course, but it's sort of slipping my mind these days - I've mostly been doing chemistry subjects, and they're not...

I can't seem to find a answer for 20.7 anywhere. Unfourtantly, I do not have the skills to latex the problem out, so I only hope someone looks in the book. My solution is that the supremum of the set of a_i 's must be finite above and the infinium is finite and greater then zero , and the b_i...

This is a question posed by NASA astrobiologist Chris McKay (who wants to put life together back from its pieces), who really wants an answer to this question since it could lead us to reconstruct ancient genomes that are billions of years old (but mutated through years of internal...

Hi best regard to all This is my first post so forgive me in any mistakes. If some one can explain to me those parts marked in red rectangles? It taught it was more convenient to post picture than typing. It's from a book that is not in English so I cut out parts with words. Many thanks to...

In Kolmogorov and Fomin's Real Analysis book, pg. 161, they make the following claim: For any vectors f,g,h in a real Hilbert space, we have \|f + g + h\|^2 + \|f - h - g\|^2 = 2\|f - h\|^2 + 2\|g\|^2. They attempt to justify this using the parallelogram law: \|x + y\|^2 + \|x -...

First of all, what's the difference between real analysis and advanced calculus? From what I've gathered, real analysis is more rigorous than advanced calculus? Second of all, what's a good book for self study for real analysis or advanced calculus? I've just finished taking my first abstract...
