What are the fundamental concepts of linear algebra?

Linear algebra is often the first course one takes where there is some emphasis on rigorous proofs. Prior courses emphasize calculation by methods that the students are told work. This is not mathematics--it is essentially arithmetic. Thus, in a sense, linear algebra is often the first "real" math course that students ever take.

Why is linear algebra important in engineering?

Answer (1 of 8): After reading through the answers and some of the replies/comments, it seems that the biggest issue is confusion over the fact that High School Algebra and Linear Algebra share the word Algebra as part of the name. So I will, …

Is Linear Algebra The hardest math class?

Linear algebra is not the hardest math class. Compared to other math courses linear algebra is harder than calculus I and discrete math but similar to calculus II in terms of difficulty. However, linear algebra is easier than most upper-level math courses such as abstract algebra and topology.Oct 29, 2021

What grade is linear algebra taught?

Students who take Algebra 1 in 7th grade can complete Calculus in the 11th grade and take an even more advanced math class, such as college-level Linear Algebra, in grade 12. On the other hand, students who want to jump off the Calculus track have other course options, such as Trigonometry or Statistics.Jan 17, 2010

Is Linear Algebra harder than Calc?

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.Oct 23, 2020

Why is linear algebra so important?

In simpler words, linear algebra helps you understand geometric concepts such as planes, in higher dimensions, and perform mathematical operations on them. It can be thought of as an extension of algebra into an arbitrary number of dimensions. Rather than working with scalars, it works with matrices and vectors.Jul 24, 2020

Is Linear Algebra a college course?

Course Overview

Due to its broad range of applications, linear algebra is one of the most widely taught subjects in college-level mathematics (and increasingly in high school).

Is Linear Algebra Post AP?

Linear Algebra is a course taken in the sophomore year in college/university, and taken after Calculus II (AP Calculus BC). The Linear Algebra course is almost never offered in high schools due to its advanced nature, and also because there is a no "AP Linear Algebra" exam.

Should I learn calculus before linear algebra?

So, for those students wishing to get ahead and get Linear Algebra in their completed column in their academic plan, you do need to complete Calculus II first, which means also completing Calculus I first, even though Linear Algebra has nothing to do with either course.

Is linear algebra pure math?

Linear Algebra is the study of properties and systems which preserve these two operations, and the following pages present the basic theory and results of this important branch of pure mathematics. There are many books on linear algebra in the bookshops and libraries of the world, so why write another?

Do engineers have to take linear algebra?

Yes. Linear algebra is required for a BS in mechanical, civil, or electrical engineering as far as the programs I'm associated with.Dec 4, 2014

What is linear algebra used for in real life?

The real life applications of linear algebra are: Used to create ranking algorithms in search engines such as Google. Used to analyse the digital signal and encode or decode them that can be the signals of audio or videos. Used to optimise in the field of linear programming.

How important is linear algebra in machine learning?

The concepts of Linear Algebra are crucial for understanding the theory behind Machine Learning, especially for Deep Learning. They give you better intuition for how algorithms really work under the hood, which enables you to make better decisions.Oct 8, 2019

Is linear algebra used in AI?

Linear Algebra or Mathematical objects are Vectors, Matrices and Tensors. Depend upon the dimensions of your data you have to choose the right object to store and process, Title diagram describes this. Before starting how to use Mathematical Objects in AI, it is better to refresh Linear Algebra.Aug 27, 2020

What is linear algebra?

with matrices and vectors, linear algebra might be defined as the study of objects where addition makes sense and maps between those objects which respect addition. An additive (i.e. linear) structure is one of the most pleasing structures one can have on a mathematical object.

Why is linear algebra so difficult?

I think linear algebra can be difficult for students because it can be a first course involving rigorous proofs. For me, linear algebra was difficult the first time around because I was not serious about academics yet and the course was difficult enough that I couldn't get by without studying.

What is the main point of linear algebra?

One main point of linear algebra is that linear equations are easy to solve. Let me explain.

What is the most application-worthy part of linear algebra?

2) the single most application-worthy part of linear algebra is principal-component analysis, also known as a million other names as every field rediscovers it and puts their own name on it. The toy example I have in my head is when you have a lot of points on a 2-D plot that falls in one line - don't you really want to think of it as a line in one dimension? Congrats, you've discovered 1-d principal component analysis ( or linear regression; I don't think of the two as much different =D).

Why is algebra important?

Algebra is useful because you can leave an expression with the variable intact and solve it for ALL values of that number. This is especially useful when:

Why does geometry fail in R?

Geometry fails. This is partially due to the way it's taught. We like to introduce vectors as real space components, which is great for matrices in R 3, but when you start taking higher dimensional spaces, attempts to visualize cause more problems than they solve.

What is the struggle with algebra?

Students who struggle with Algebra, while succeeding in earlier branches of math, tend to be the ones who struggle with abstraction.

When is linear algebra useful?

It's useful when you have many moving parts in an engine, concentrations of multiple chemicals in a test tube , many regions of atmosphere in a climate simulation, prices of stocks in a market, etc..

Why is linear algebra important?

Because linear equations are so easy to solve, practically every area of modern science contains models where equations are approximated by linear equations (using Taylor expansion arguments) and solving for the system helps the theory develop.

What is the importance of understanding linear algebra?

Understanding the tools of linear algebra gives one the ability to understand those theories better, and some theorems of linear algebra require also an understanding of those theories ; they are linked in many different intrinsic ways.

What are the applications of linear equations?

In the abstract, it allows you to manipulate and understand whole systems of equations with huge numbers of dimensions/variables on paper without any fuss, and solve them computationally. Here are some of the real-world relationships that are governed by linear equations and some of its applications: 1 Load and displacements in structures 2 Compatability in structures 3 Finite element analysis (has Mechanical, Electrical, and Thermodynamic applications) 4 Stress and strain in more than 1-D 5 Mechanical vibrations 6 Current and voltage in LCR circuits 7 Small signals in nonlinear circuits = amplifiers 8 Flow in a network of pipes 9 Control theory (governs how state space systems evolve over time, discrete and continuous) 10 Control theory (Optimal controller can be found using simple linear algebra) 11 Control theory (Model Predictive control is heavily reliant on linear algebra) 12 Computer vision (Used to calibrate camera, stitch together stereo images) 13 Machine learning (Support Vector Machine) 14 Machine learning (Principal component analysis) 15 Lots of optimization techniques rely on linear algebra as soon as the dimensionality starts to increase. 16 Fit an arbitrary polynomial to some data.

What is the motivation to study linear algebra?

Your beginning motivation to study linear algebra is to put together what you initially learn in (mathematically) geometry and calculus and in (education) high school, college, or even first year or second year of university.

What happens if you use only the first two terms of the Taylor expansion of f?

If you use only the first two terms of the Taylor expansion of f, you have a linear approximation to your function f:

What is one application of linear algebra?

One application of Linear Algebra is in the use of eigenvalues.

What is the essence of linear algebra?

At its core, Sanderson’s ‘ Essence of Linear Algebra ’ series seeks to introduce, motivate, and conceptualise many of the basic ideas around linear algebra in terms of linear transformations and their associated visualisations. As it turns out, this is a really helpful way to get your head around many of the core fundamentals.

What is linear transformation?

A linear transformation is a way of changing the shape of a ‘space’ (in this case, the 2D plane), in such a way that: Keeps parallel lines parallel. Maintains an equal distance between parallel lines that were equally spaced to begin with. Leaves the origin at the origin.

What does a 2x2 matrix represent?

We’ve just demonstrated that a 2x2 matrix will necessarily represent some kind of linear transformation in 2D space. In particular, for a given matrix [ [a, b], [c, d]], the vectors [a, c] and [b, d] represent the coordinates of ‘transformed î ’ and ‘transformed ĵ ’ respectively.

How many types of linear transformations are there?

Broadly speaking, this gives us three different types of linear transformations that we could do:

What happens when theoretical foundations are predicated on rote learning and plugging numbers into formulae?

If your theoretical foundations are predicated on rote learning and plugging numbers into formulae, without a deeper appreciation and understanding of what’ s actually going on, then they tend to fall down under the weight of something as heavy as, let’s say, machine learning.

Is linear algebra problematic?

Going from the ‘how’ to the ‘why’. This slightly utilitarian attitude to teaching linear algebra is clearly problematic. Mathematics is a discipline that relies on an ‘incremental’ learning — gaining new knowledge often requires you to build upon what you already know.

Who made 3Blue1Brown?

At this point, I’ll mention that this blog was heavily inspired by a series of videos made by Grant Sanderson (a.k.a. 3Blue1Brown ). For those unfamiliar with his work, Sanderson creates really nicely animated videos in a way that makes complicated mathematical subjects accessible to the educated layman (his videos explaining neural networks and cryptocurrency are well worth your time).
