Differential Equations vs Linear Algebra

Click For Summary

Discussion Overview

The discussion revolves around the comparison between Differential Equations and Linear Algebra, particularly in the context of their difficulty, relevance, and applications in various fields. Participants explore the implications of taking both courses simultaneously as part of an engineering curriculum.

Discussion Character

  • Debate/contested
  • Conceptual clarification
  • Exploratory

Main Points Raised

  • One participant notes the content of both courses, highlighting topics in Linear Algebra such as matrix theory and eigenvalue problems, and in Differential Equations such as first order equations and Fourier series.
  • Another participant suggests that Linear Algebra is more fundamental and broadly applicable compared to Differential Equations, which they view as a collection of methods specific to solving differential equations.
  • A participant inquires about the applications of interest, indicating that different fields prioritize either Linear Algebra (e.g., computer vision) or Differential Equations (e.g., control theory).
  • One participant expresses uncertainty about their career direction but mentions interests in computer engineering and physics, particularly in areas like microprocessors and quantum physics.
  • Another participant asserts that both Linear Algebra and Differential Equations are extensively used across various scientific disciplines, challenging the claim that they are not broadly applicable.

Areas of Agreement / Disagreement

Participants express differing views on the fundamental nature and applicability of Linear Algebra versus Differential Equations. There is no consensus on which course serves as a better prerequisite or is more essential for various fields.

Contextual Notes

Participants' claims about the applicability of the subjects may depend on specific career paths and fields of study, which are not universally agreed upon. The discussion reflects a range of perspectives on the relevance of each subject in different contexts.

Linear Algebra and Vector Analysis for Engineers

Matrix theory, linear equations, Gauss elimination, determinants, eigenvalue problems and first order systems of ordinary differential equations, vector field theory, theorems of Green, Stokes, and Gauss.

Methods of Differential Equations
First order equations; higher order linear equations with constant coefficients, undetermined coefficients, variation of parameters, applications; Euler's equation, series solutions, special functions; linear systems; elementary partial differential equations and separation of variables; Fourier series.

This fall I might be able to take both courses. According to our school's sample curriculum, both courses are taken simultaneously in upper sophomore year (spring). Of course it is upon the decision of the students.

My questions are: how hard are both courses? Should I take both? Between the two, which one looks more like a prerequisite (preparation) for the other?

Thank you.

If I were to give an opinion on which one were more "fundamental", then I'd say the linear algebra one. And that would certainly be the more useful subject to know (depending of course on what you intend to go on and do).

Methods of solving differential equations tend to be just that: a list of different methods which work in different cases. Although being able to solve differential equations is essential for a physicist, engineer etc, it won't help in any area other than differential equations. Linear algebra, on the other hand, is used all over the place.
 
Thank you mrbohn1. I am a CUNY City student.
 
What applications are you interested in? Some fields use linear algebra heavily (computer vision) and some field use differential equations heavily (control theory).

I am still not sure yet. But I believe as a computer engineering major (and also intended doing physics as well) I'd like to work in fields like electronic devices, such as microprocessor.

I guess I should say physics in general, but for career-wise, solid states, quantum physics.
 
"What applications are you interested in?"
I am interested in Linear algebra and defferential Equations although it is not really useable in any other fields of works. . .

What? Both Linear Algebra and Differential Equations are used extensively in Physics, Chemistry, Biology, ... any science, as well as Economics and Business Administration!
