how hard is a proof-based linear algebra course

So essentially a proof based Linear Algebra course would be the same level of difficulty as an Abstract Algebra and the proofs, though different, are not so difficult. I'd say so. Depends a bit on a person's ability of abstraction.

Full Answer

Is Linear Algebra a difficult course?

Linear algebra is one of the most difficult courses that most STEM majors will study in university. Linear algebra is not an easy class because it is a very abstract course and it requires strong analytical and logical skills.

Is Linear Algebra a proof based course?

Welcome to Linear Algebra for Math Majors! This is a rigorous, proof-based linear algebra class. The difference between this class and Linear Algebra for Non-Majors is that we will cover many topics in greater depth, and from a more abstract perspective.

How important are proofs in linear algebra?

However one of the major themes of modern mathematics is the classification of structures and objects and using the proofs from linear algebra is an important tool to tell us when two objects are apparently different objects or are indeed the same.

Is Linear Algebra more difficult than calculus?

Linear algebra is easier than elementary calculus. In Calculus, you can get by without understanding the intuition behind theorems and just memorizing algorithms, which won't work well in the case of linear algebra. By understanding the theorems in linear algebra, all questions can be solved.

How do you get good at proofs?

Write out the beginning very carefully. Write down the definitions very explicitly, write down the things you are allowed to assume, and write it all down in careful mathematical language. Write out the end very carefully. That is, write down the thing you're trying to prove, in careful mathematical language.

What is a proof-based math class?

Students learn to construct formal proofs and counter-examples. By contrast to example-based courses where general principles emerge gradually from hands-on experience with concrete examples, in these courses definitions and techniques are presented and developed with maximal abstraction and generality.

How do I get better at linear algebra?

An Intuitive Guide to Linear AlgebraName the course Linear Algebra but focus on things called matrices and vectors.Teach concepts like Row/Column order with mnemonics instead of explaining the reasoning.Favor abstract examples (2d vectors! 3d vectors!) and avoid real-world topics until the final week.

So we're left with a times the identity matrix.

Should I learn calculus before linear algebra on a finite dimensional space V?

You don't need calculus as a prerequisite to linear algebra. (Some of the exercises in linear algebra might mention calculus; e.g. the linear nature of the differentiation operator. But it is possible to learn linear algebra without that.)

What is the toughest math?

1. Algebra: Algebra is a branch of mathematics that studies symbols and the rules that control how they are used.

What is the hardest math course?

In most cases, you'll find that AP Calculus BC or IB Math HL is the most difficult math course your school offers. Note that AP Calculus BC covers the material in AP Calculus AB but also continues the curriculum, addressing more challenging and advanced concepts.

What level of math is linear algebra?

And, linear algebra is a prereq to the math reasoning class, also known as intro to proofs. And, that class is the prereq to 75% of all the upper level math classes. So, it's important to take it early if you want to take other math classes.

What are proofs in linear algebra?

A proof is a sequence of statements justified by axioms, theorems, definitions, and logical deductions, which lead to a conclusion.

What are proofs in algebra?

An algebraic proof shows the logical arguments behind an algebraic solution. You are given a problem to solve, and sometimes its solution. If you are given the problem and its solution, then your job is to prove that the solution is right.

How many solutions does a consistent linear system of 3 equations and 4 unknowns have Why?

A homogeneous system of 3 linear equations in 4 unknowns always has a solution, in fact, always has a non-trivial solution, a solution where the unknowns are not all zero.

How to prepare for algebra class?

You can prepare for the class by watching a linear algebra playlist on Youtube or you could read a self-study book. I would highly recommend this book on Amazon if you want to self study the class it’s also good as a second book for the class anyway.

Why do you read the relevant chapter before doing homework?

By reading the relevant chapter before doing the homework you will be able to reinforce what you learned in class, you’ll have a more intuitive understanding and you will find it easier to solve the questions.

Is linear algebra easier to learn?

While linear algebra is considered as an easier math class you will still need to study a reasonable amount outside of class.

Is linear algebra harder in less selective colleges?

So, you will likely have an easier time at a less selective college. With that being said, that is not a rule. Sometimes, linear algebra at less selective colleges can be very difficult mainly depending on the professor teaching it.

Does algebra depend on the professor?

It will depend a lot on the professor. The difficulty of any college class will depend a lot on the professor and these is especially the case with linear algebra. The professor will normally dictate the pace of the class, what gets covered, what goes on exams and what gets covered in the homework. Some professors will tell you to know everything ...

Is linear algebra hard?

So, is linear algebra a hard class? Compared to other math classes, linear algebra is generally considered as being one of the easier college-level math classes.

Is linear algebra taught at colleges?

Another thing to consider is the college. Linear algebra taught at colleges with a low acceptance rate tend to get through a lot of material quickly. At these colleges, you will likely find the class to be more challenging and you’ll have to spend more time studying. Whereas, linear algebra taught at less selective colleges will not tend ...

What level of Math is Linear Algebra?

Linear algebra is considered intermediate-level math. Linear algebra is one of the toughest courses along with calculus II that STEM most majors will encounter. However, linear algebra is not a very advanced course since there are several more advanced courses such as abstract algebra and topology.

Is Linear Algebra Different than Algebra?

Algebra is a general term and it includes a variety of different forms including elementary algebra, linear algebra, and abstract algebra. Linear algebra focuses on structures that can be described by a system of linear equations.

Is there Calculus in Linear Algebra?

There is almost no calculus in a basic linear algebra undergraduate course. However, as you progress into more advanced mathematics you may find linear algebra problems requiring calculus and vice versa.

Is Linear Algebra worth taking?

Linear algebra is absolutely worth taking. If you have to choose between linear algebra and any other math course then selecting linear algebra is a no brainer. Linear algebra is one of the most important undergraduate course for STEM majors.

Is Linear Algebra the Most Useful Math?

Linear algebra is the most useful math along with calculus when it comes to the math courses taught in college. However, arithmetic, basic algebra, and trigonometry taught in primary, middle, and high school are more useful than linear algebra.

Is Linear Algebra Hard?

Linear algebra is hard. Linear algebra is one of the most difficult courses that most STEM majors will study in university. Linear algebra is not an easy class because it is a very abstract course and it requires strong analytical and logical skills.

I'm self-teaching myself highschool algrebra and doing well now, but I don't understand one seemingly simple question in my workbook. Is the answer in the textbook wrong?

Hello, I think I have mastered high school algebra after practicing for around 19 hours in the last two days. However, there's just one question I can't seem to understand that's seemingly easy:

Any recommendations for mixing learning math and programming

Does anyone know of any resources that encourages the usage of programming knowledge to solve math concepts? Like a website that can utilize your ability of coding to somehow make learning easier.

Im really interested in math, but im shit doing calculus

Hi, my name is Florence and im a 15 year old person who wants to be a physicist but knows nothing about DOING a calculus and not just read about the concept of it. I always hated math cus i felt frustrated for not knowing how to solve my homework or because i couldnt think of a way of resolving the calculus.

What is a proof-based class?

What I would call a proof-based class is one where concepts are introduced from first principles, that is a set of axioms or a ground truth, from which all other concepts are proven through logical steps and arguments. These are commonly found in second year pure math tracks, such as Abstract Algebra and Real Analysis.

Definitions, definitions, definitions

Whenever a new concept or terminology is introduced in these classes, it is introduced with a concrete mathematical definition. The first trap I see students fall into is when they see a new phrase, they don’t ask themselves what it means mathematically.

Understanding contrapositives and proof by contradictions

Sometimes the best way to prove a statement is to look at it in a different light. One common and helpful way to reformulate a statement is to look at what’s called the contrapositive. Given a statement of the form, “A implies B”, the contrapositive is the statement “not B implies not A”.

Practice makes perfect

Just like any other skill, reading and writing proofs are skills that can be learned with more and more practice. I would highly recommend doing the problems at the end of a chapter or trying to reprove a theorem using only what you remember.

Conclusion

A proof-based class can be a daunting task, but it gets easier the more time you put into it. Remember to always ask yourself for definitions of new concepts, and approach proving statements from multiple perspectives. Stay confident and good luck!
