Should I take more Linear Algebra?

Click For Summary

Discussion Overview

The discussion revolves around the necessity and value of taking additional courses in linear algebra, particularly in relation to graduate school requirements and its applications in various scientific disciplines. Participants explore the differences between combined courses in linear algebra and differential equations versus separate, dedicated courses in linear algebra.

Discussion Character

  • Debate/contested
  • Conceptual clarification
  • Exploratory

Main Points Raised

  • Some participants suggest that a combined course in linear algebra and differential equations may not provide a comprehensive understanding of linear algebra, as it primarily focuses on applications to differential equations.
  • Others argue that separate courses for linear algebra and differential equations would be more beneficial, as linear algebra has broader applications beyond just solving differential equations.
  • One participant notes that their experience in a linear algebra course involved significant vocabulary and proof work, indicating a shift from the calculus approach.
  • Another participant emphasizes the importance of linear algebra across all scientific disciplines, sharing a negative experience with an abstract teaching approach that lacked real-world applications.
  • Some participants mention the relevance of linear algebra in specific fields, such as physics and mathematics, suggesting that a deeper understanding may be necessary for those pursuing advanced studies in these areas.
  • One participant highlights the potential benefits of self-study in linear algebra, especially if formal courses do not meet expectations.
  • A later reply suggests that for those interested in mathematics graduate programs, studying more abstract texts may be advantageous, while also noting the importance of practical applications for physical sciences.

Areas of Agreement / Disagreement

Participants express a range of opinions on the necessity of additional linear algebra courses, with no clear consensus on whether a combined course is sufficient or if separate courses are preferable. There are competing views on the effectiveness of different teaching approaches and the relevance of linear algebra in various fields.

Contextual Notes

Some participants mention limitations in their courses, such as not covering all material or focusing too much on abstract concepts without practical applications. There is also a recognition of the varying importance of linear algebra depending on the specific scientific discipline being pursued.

It looks like a lot of grad schools specify a course in linear algebra. Would a course on Linear Algebra and Differential Equations be sufficient (basically Calc iv, taken after the introductory calc sequence)? Or, would an upper-level course devoted just to linear algebra be desired on top of calc iv?

(It seems like it would involve too much "pure" math for physical science, but that's just my impression...)

My schools (UMass/GCC) offer both a combination Diff-Eq/Linear class as well as individual entry level Diff-Eq and Linear classes (along with higher level classes).

I took a 4-credit Linear Algebra class (I'm taking Diff-Eq this spring) and we couldn't cover everything in the text. I'm working on reading the rest on my own due to the usefulness of the material. We used David Lay's text.

EDIT: I did find the course to be fairly different from my Calculus courses. We spent a good amount of time learning vocabulary and doing proofs. Proper wording is incredibly important, as many things that sound similar are drastically different. We covered chapters 1-6, but didn't get into 7 or 8.

If you take linear algebra with differential equations you will most likely only see linear algebra and how it used to solve certain differential equations. However, linear algebra has many more applications and useful theorems than simply to differential equations. If I had the choice, I would pick separate courses for both.
 
Im at community college and it has its own 4 unit class devoted to it which I am taking right now. Very interesting class but has been very difficult for me compared to calculus.
Like Nick was saying there's a lot of vocab and I also think its a lot more abstract.
 
What kind of grad school (as in which major) do you intend to continue on to?
 
I find linear algebra very important no matter what scientific discipline you go into. My school required me to take a 200 level lin-alg class along with a separate diff-Q course. Although my lin-alg class did a very crappy job of teach since it only taught in the abstract mathematical sense which nothing applicable to the real world. Honestly, if your lin-alg classes are anything like mine your better off learning it on your own.

no, i think for going to mathematics grad school such a course like your "abstract mathematical" LA using maybe axler, halmos, or roman, is much much better than engineering one

if math grad school, then read axler, halmos, roman, mathwonk notes, etc., for the pure

abut yes he can also learn this on his own :D

also if maybe physical sciences, physics, etc., then you can learn a very upper algebra like representation theory, etc., for physics, quantum mechanics maybe

maybe also he will bored if engineering one

so doing is not bad idea

also maybe you can spend some time to learn MATLAB when are older, but when are older you miss the opportunity to study the pure mathematics so you can have very stsrong conceptual idea of it which is not bad idea

If you are studying physics, a full semesters course would be extremely helpful and necessary. I cannot think of a course in QM that would not use many of the concepts taught.
 
Yes, it's fun.
