math

Mathematics is the body of knowledge centered on such concepts as quantity, structure, space, and change, and also the academic discipline that studies them. Benjamin Peirce called it "the science that draws necessary conclusions".[2] Other practitioners of mathematics maintain that mathematics is the science of pattern, and that mathematicians seek out patterns whether found in numbers, space, science, computers, imaginary abstractions, or elsewhere.[3][4] Mathematicians explore such concepts, aiming to formulate new conjectures and establish their truth by rigorous deduction from appropriately chosen axioms and definitions.[5]....

100% Q: Math????????????
I'm so confused right now. I'm in 7th grade and i was put into an advanced placement math class and i have to get a b and above to stay in it. Well i don't know what happened im always good in math but lately my quizzes have been very bad but my tests very good. There is only till march 7th to get my grade up from i think a c- to at least a b. I'm really worried but i dont know why im having a problem. It's just that when i look at my parents who are very good at math and then you look at me whose doing horrible in it i just wish i was smarter. I don't want to get kicked out of the class. But everything shows that im not smart and i want to continue in the advanced path i don't want to go away from that i like it. Any Advice?
A:It may not be a problem of being smart or not. Math is a subject that is taught with a base and built off of that base. If you have changed math levels you may have missed some of the teaching that the others have already had. Try getting some help from other classmates or a tuitor. They may be able to show you what you may have missed!

100% Q: What advanced math classes should I take for economics?
I'm an economics major, and I'm not sure exactly what sort of math classes I should be taking. I'm planning on graduating next year, and I am interested in the most useful math classes to take to prepare myself for grad school in economics. I'm taking the analysis courses with Rudin's book this fall and spring, Applied Linear Algebra this fall, and then I want to take topology as well. But I want to take more math, should I do things like numerical methods, fundamental structure of Algebra, or Differential Equations or what? I'm actually only a Junior, so I have quite a bit more time for classes, but I'm currently taking the basis higher level stat classes, and will probably need to decide which classes to take there, but I think I have more of an idea what stat classes I'm going to take, and I've completed the calculus series. They just offer a higher level series of courses on elementary partial differential equations and I'm not sure if they're worth taking or not.
A:First of all, you should definitely stay focused on applied math classes and don't take too many pure math classes unless you are interested in math. Now, the applied math classes for an econ major would be undergraduate trimester calculus course (which sounds like you have taken). Then linear algebra, ordinary differential equations, AND some sort of an intro to applied math class (which will be an advanced version of calculus 3). Notice this class is not the same as the analysis courses you are taking which are also called advanced calculus by some people. Numerical analysis/methods will definitely be useful (in fact a lot of recent discoveries in numerical analysis were made by economists and weather forecasters). Topology is useless for economics. Further analysis courses will be useless too. Complex analysis will be useless. A PDE (partial differential equations) course might be useful. Algebra will be completely useless for you. Further, topics at the top of your list would be statistics and probability. Definitely take the complete sequence of upper division statistics (after lower division statistics). Definitely take as many probability courses as you can and learn about probabilities distribution, stochastic processes, markov chains, markov processes, law of large numbers, random variables, and such things. If you really want to nail the math, then in analysis, you should (you don't have to) go all the way up to real analysis with lebesgue integration. The problem is that usually, you need to finish all real analysis courses before lebesgue integration and sometimes topology is also a prerequisite. You need to do real analysis, single variable calculus, multivariable calculus, calculus on manifolds, and topology to get into a class with lebesgue integration. If there is anyway you can take the class without going through everything, or if there is an easier version available (which is NOT for pure math majors) then definitely take it. Lebesgue integration and measure theory is a basis for probability theory.

100% Q: How good in math should I be to become a civil engineer?
I am starting Civil engineering school in the fall but I am a little worried that I am not good enough in math. I have always made A's and B's in algebra, geometry, and finite math, but I have been taking an online Trig class and I am having a hard time teaching myself. I think I could do better if I was in an actual class because I learn better when I am showed but that was not an option. I want to work with the department of transportation and development so I am not sure if I will be doing more design or more supervision and inspection. Therefore, I have no idea how much of this stuff that I am being taught will ever be applied. But I am getting a little discouraged that I am not advanced enough in math to be a successful engineer. I also seem to have trouble retaining information if I do not use it and apply it and this is a bit discouraging also. Should I consider another field or is all of this in my head?
A:You need to develop a proficiency in mathematics. A Civil Engineer is in volved with trigonometry problems on almost a constant basis. with a good grounding in algebra, geometry and Trig you will be able to handle most problems that you meet in your carreert. However the university is going to require at least 2 and probably 4 semester of Calculus, Advanced algebra and maybe differential equations before you earn a degree. The truth of the matter is that this is overpreparation for most people except the tiny minority that goes into research work. From my own experience I have only met one Civil Engineer who said that he has ever used calculus in his work and I have only used it a half dozen times. If you plan on working for DOT you will probably never have the occasion to use calculus on the job but I guarantee trig is a must.

100% Q: How much math do you really need to study social networks?
Social Network Analysis works with graph theory, which comes from math. But how much math do you really need to know in order to have the necessary tools for working in this field? What subjects should one master? Calculus, statistics.. ?
A:If you're really serious about working with this particular theory set, you do need to have a good command of basic maths, including the use of statistics for social research. There are, however, related theory sets that use less math and can also be used to achieve very similar descriptive goals. Look into actor-network theory, for instance, which is a child of sociology just like social network analysis, but pays more attention to flows of power, rather than proximity.

100% Q: How many math classes do you have to take in college if you want to major in cinematogrophy?
Just wondering because im a freshman at a community college, and im getting all my reqired classes out of the way. And i wanna know how many maths i have to take because i hate math and i suck at it.
A:It depends on your school and your program of study. Most university have something called a DARS program on the internet that you can log into and it will tell you what classes you've met requirements for so far and which classes you still need to take (including electives where there is some leeway for you to choose which ones). Most non-science Liberal Arts degrees have you take up to Algebra. But again, check with your specific program.
