Introduction to Linear Algebra, 5th Edition

Linear Algebra Problems in Lemma My friend Pavel Grinfeld at Drexel has sent me a collection of interesting problems -- mostly elementary but each one with a small twist. These are part of his larger teaching site called LEM.MA and he built the page for this website linked to the 5th edition. The H.264 Video Standard (promised in Section 7.1 of the book) This video standard describes a system for encoding and decoding (a "Codec") that engineers have defined for applications like High Definition TV. The words "motion compensation" refer to a way to estimate each video image from the previous one. It is ideas like this -- easy to talk about but taking years of effort to perfect -- that make video technology and other technologies possible and successful.

Time Series Analysis and Forecasting with ARIMA - Kanoki

In this post we will discuss how to do a time series modelling using ARMA and ARIMA models. Here AR stands for Auto-Regressive and MA stands for Moving Average Before we start discussing the ARIMA models, we should know the stationarity of time series Stationary Process A time series is called to be stationary if there is no change in mean, variance and covariance of the observations over a period of time.

The process remains in a state of statistical equilibrium In other words a process is said to be stationary if the joint distribution of observations does not change and remain same when the origin of time is shifted by amount k This means that the mean and variance are constant and do not depend on time. Stationary Process Non Stationary Process What is ARIMA? ARIMA stands for Auto-Regressive Integrated Moving Average and it’s one of the widely used time series models for forecasting ARIMA Modelling Procedure Load Dataset.

The Map of Mathematics. Mathematics. MSC 2010 Classification Codes. Reference. Cormullion. This post was inspired mostly by the arrival of the new Julia package Literate.jl by Fredrik Ekre.


Literate lets you write a Julia source file, a Markdown blog post, and a Jupyter notebook all at the same time. It’s magic, or, at least, indistinguishable from magic… As a result, you might be able to find a Jupyter notebook version of this Markdown-converted Julia source file somewhere nearby (look in the github repo for this blog, perhaps). The code uses the following packages, Literate, Luxor, Colors, Roots, Fontconfig, DataFrames, Iterators, ColorSchemes, and should work in Julia v0.6 (some packages such as Colors have yet to be updated to work with version 0.7). Luxor provides some support for Bézier curves, but there’s no room for any more documentation—it’s already too big. So the intention of this post is to provide some of the missing information about what’s up with Bézier curves and how you might use them.

Historical background the designers were astonished and scandalized. Essential mathematical GIFs that will make mathematics finally make sense. And I can say that fortunately, there’s actually so many ways to use GIFs in our classrooms.

Essential mathematical GIFs that will make mathematics finally make sense

Although using GIF animations as a technological tool that is very rare in mathematics education, you can do things with these animations that you can’t do with plain text. For instance, instead of telling the students the directions over and over again, just make a GIF for each step. And then the students will see and know it’s important and remember all those parts of a solution or formula.

You will keep your students learning and laughing. It could be a cool way to be the coolest teacher at your school. If you are good so far, let’s take a look at some beautiful mathematical GIFs and learn! What is π/pi and why is it 3.14something? Let’s try to measure a circle. Even the students only need the first 2 digits of π, tens of scientists and mathematicians are trying to figure out the mystery of π.
