Studying Topics and books - Intro. Linear Algebra & Differentl. Equatns

AI Thread Summary
The discussion highlights concerns about the dilution of content in "Introductory Linear Algebra & Differential Equations" courses, which are often condensed into a single semester following Calculus. This course typically serves as a terminal math class for students who may not pursue further mathematics, leading to a superficial treatment of various topics. Key areas of focus for the Linear Algebra component are sought, particularly regarding essential topics that should be thoroughly covered. Additionally, participants are interested in recommendations for textbooks that effectively support the curriculum of these combined courses. A specific textbook currently used in one institution is mentioned, which has received mixed reviews from students, indicating a divide in its effectiveness and reception. The primary goal of the course is emphasized as equipping students with methods for solving simple ordinary differential equations (ODEs) with constant coefficients, transforming them into algebraic equations.

The courses called "Introductory Linear Algebra & Differential Equations" are potentially
diluted too much in order to form into a one-semester course; the one which often follows
the third semester of Calculus. This becomes a terminal Math course for students who will
usually not go further with Math, and so some topics are given far less treatment in the
effort to help the students more comfortably earn their credit.

Since these combination courses de-emphasize so many topics, could anyone tell us exactly
which topics need to be well developed for this kind of combination course, especially in
regard to the Linear Algebra portion of the course? Also, which textbooks, by author and
title, are some of the best ones to use for these combination Linear Algebra & Differential
Equation courses? (I gave away my book many many years ago, having no further use for it at
the time, and I do not remember its title or authors)

I believe that the key point of such a course is to develop the
methods for solving simple ODEs with constant coefficients
... effectively turning these differential equations into algebraic equations.
 
Hey, I am Andreas from Germany. I am currently 35 years old and I want to relearn math and physics. This is not one of these regular questions when it comes to this matter. So... I am very realistic about it. I know that there are severe contraints when it comes to selfstudy compared to a regular school and/or university (structure, peers, teachers, learning groups, tests, access to papers and so on) . I will never get a job in this field and I will never be taken serious by "real"...
TL;DR Summary: I want to do a PhD in applied math but I hate group theory, is this a big problem? Hello, I am a second-year math and physics double major with a minor in data science. I just finished group theory (today actually), and it was my least favorite class in all of university so far. It doesn't interest me, and I am also very bad at it compared to other math courses I have done. The other courses I have done are calculus I-III, ODEs, Linear Algebra, and Prob/Stats. Is it a...
