SUMMARY

This discussion focuses on learning to construct proofs in the context of a Theory of Linear Algebra course. Participants emphasize the importance of understanding theorems and suggest "Problem Solving" by C. Larson as a valuable resource for beginners. Key strategies for constructing proofs include defining problems based on learned definitions, using counterexamples, and employing techniques such as recursion and symmetry. The consensus is that familiarity with theorems allows for more efficient proof construction over time.

PREREQUISITES
  • Understanding of basic linear algebra concepts
  • Familiarity with mathematical axioms and definitions
  • Knowledge of proof techniques such as induction and contradiction
  • Experience with theorem application in mathematical contexts
NEXT STEPS
  • Read "Problem Solving" by C. Larson for foundational proof techniques
  • Study mathematical induction and its applications in proofs
  • Explore counterexample strategies to strengthen proof arguments
  • Practice defining problems using previously learned definitions and theorems
USEFUL FOR

Students in upper-level mathematics courses, particularly those studying linear algebra, and anyone seeking to improve their proof-writing skills.

so, I am in my first upper level math course beyond required calculus and the introductory linear algebra class. I don't know if it's just a great jump or if I slept through something, but suddenly everything is all about doing proofs. I'm okay with that, and I think it's fabulous because proofs seem to yield deeper conceptual understanding, but I have no experience whatsoever with writing/constructing proofs. I can memorize axioms and whatnot, but then how do I get started? anyone have any good texts on proof writing or know of any resources that could help me? I'm clueless here!

I don't know if it makes a difference (with regards to what kind of proof I should study) but the class is Theory of Linear Algebra. I love the topic, just have no idea how to prove things for every case... :blushing:

yes there is a good book called Problem Solving by "C" Larson. Not sure if the C is the write letter.

the main way that I learned how to do proofs was to cram allt he theorems on one page. granted that you actually have to understand these theorems.

The straight forward method is to just rearrange your problem by regurgitating each step via one the theorems that you have learned up till that point.

Larson's Book outlines steps you should take to rearranging a given problem in such as looking for a counterexample(contradiction), recursion(can't remember the proper term...oh induction), look for symmetry and parity.

At the beginning of it all though try to define your problem based on all the previous defintions that you have learned.

...onc eyou become more accustomed to knowing some theorems and techniques then you can skip the majority of steps.
