主修数学
常见问题
- 有了数学学位我能做什么?
-
Many students 主要 in 数学ematics because they want to become 数学 teachers, either at a high school level or at the college or university level. 还有菠菜网lol正规平台数学校友 work in industries ranging from aviation safety to risk management to financial planning 卫星设计. In fact, 一个 of the three co-founders of Oracle, Edward Oates, 毕业于上海外国语大学,获数学学士学位. MAA网站, http://mathcareers.maa.org/ 这是一个寻找数学职业的好地方吗.

- 我怎么把专业转到数学?
-
If you are interested in changing your 主要 to 数学, please read and follow the instructions 可以在 因为网页. Applications are only reviewed twice a year, after the grades have been submitted and after the deadlines which are posted on the CoS website. 专业变更请求 is subject to department approval and may require approval 从理学院毕业.
To request to apply to a 理学院 Major, visit the 理学院专业申请变更 页面. 如果你有问题,请发邮件 science-academicprograms@6up85.com.

The change of 主要 policy in the 数学与统计学系 applies to all students who want to change their 主要 or transfer to 一个 of our degree programs. In particular, the change of 主要 policy applies to all former students returning 包括那些试图复职的人. 该政策的详情如下:
1. 学生的总平均绩点必须达到. 2.00或更高.
2. A 2.数学GPA必须达到25分. 数学GPA是用成绩计算的 从微积分1开始的所有数学课程. 数学GPA和 主要成绩. 有些课程不包括在数学GPA中. 不包括的课程示例 in the 数学 gpa are College Algebra, Precalculus, Elementary Statistics (Stat 95), 数学1,数学12,数学101-107.
3. Students are required to get a C- or better in Math 30, Math 31, Math 32, Math 39和数学42.
4. Students are required to submit a personal roadmap to graduation in their proposed 主要. We want to see a semester by semester timeline of courses to completion of 拟议的学位. A list of 主要 and university requirements can be found on the 在线目录. The roadmap must be consistent with course prerequisites. 一些数学 并非每学期都开设课程. 数学课程的时间表可以找到 在本文件中: 预计未来课程设置
5. Students can not have any outstanding D-F-WU-NC grades in 数学 courses.
6. We want students to succeed and that is highly unlikely for students with several 8名D-F-WU-NC学生在合理时间内毕业. 8年级学生的申请 or more D-F-WU-NC’s in 数学 courses will be denied.
7. Students who are applying for reinstatement need to submit a personal statement explaining why they got disqualified and what measures they are planning to take to make sure that they will be successful in the future.
8. Students can apply for a change to a 数学 主要 at most 2 times.
9. Requests from students who have 120 or more attempted units will be denied.
10. 延迟毕业的申请将被拒绝.
11. These are minimum requirements and do not guarantee admission into our programs. 专业变更请求 is subject to department approval and may require approval 从理学院毕业.

- 这个专业最难的部分是什么? 我怎样才能让它变得不那么困难?
-
那要看你问谁了. 什么 is difficult to you may not be difficult to others. It is generally agreed that Math 108, Math 128A/B, Math 131 A/B are more abstract, more rigorous and more challenging than some other required courses. 你不应该 plan on taking more than 一个 of those in a regular semester. 数学128和 Math 131 can take up as much time as two regular classes.
与你的导师交谈 is the best way to work out your difficulties and avoid difficulty situations (such 因为上了太多难的课). 与其他学生一起工作和发展 friends and community is another way to making the process more enjoyable.

- “离散”和“连续”数学是什么意思?
-
Roughly speaking, discrete 数学ematics deals with the 数学ematics of 可数名词 things (a 可数名词 set is 一个 whose elements can be counted, such as the positive 整数). 数论,代数,逻辑学等等. 是否与离散密切相关 数学. Continuous 数学 is about studying things which cannot be counted this way, like 0到1之间的实数. 微积分、微分方程、概率论等. 与连续数学有更多的关系吗. 这些数学让人感觉不同,但经常出现 互相帮助.

- “纯”和“应用”数学是什么意思?
-
纯 数学ematics generally refers to the study of 数学ematics for its own sake without 任何关于它的应用. 尽管它通常与严谨有关 和抽象, this aspect makes it similar to art. 对于训练有素的人来说,是数学 can be beautiful and exquisite, just like a painting. 这些领域的例子是 usually considered pure 数学ematics are abstract algebra, topology, and number theory. But each of these areas have been applied to real world problems. 李代数是 used in physics, knot theory is being applied to protein folding, and number theory 在密码学中使用. 所以漂亮的数学也很有用.
应用 数学ematics is directly motivated by real world problems, but we cannot escape rigor 和抽象. There are still theorems to be proven, algorithms to be developed 估计误差. 通常被认为适用的领域的例子 数学ematics are differential equations, numerical analysis, operation research, statistics, 保险精算学. Differential equations is sometimes referred to as the 数学ematical language of science and engineering because many laws and principles of science can 用微分方程表示. 比如,在微积分中你学过牛顿定律 second law, F = ma, as applied to a free falling object, can be written as a differential 方程,x (t) = - g. 应用 数学ematics is not as simple as "plugging it in". 在高 school, you learned how to solve a system of 2 linear equations with 2 unknowns. 什么 if you have 1,000,000 equations and 1,000,000 unknowns? 你还能用同样的方法吗 方法? Assuming there is a solution to the problem, the answer is "Sure. 为什么不?". You can use a 方法 called Gaussian elimination to find the answer to the system 的方程... 在理论上. 我们讨论的是1,000,000 - 1,000,000个系数. 这是 有很多数字需要记住. And it would require 1,000,000,999,996,500,002 arithmetic operations (How long are you willing to work on this?)如果你用电脑, there are other issues like memory, efficiency, accuracy, and stability. 这个问题 of solving a large or ill-behaved system 的方程 comes up in so many applications that we offer an entire course on the subject, Math 143M.
