Applying Linear Algebra to Differential Equations

Learners find the common point of a linear and quadratic system given a graph of the system. Then they find a specific point located only on the parabola.

If your class has a grasp on the concept of graphing systems of equations and has worked with inequalities, then it's time to expose them to the wonders of graphing systems of inequalities. Using various colors and a graph, Sal explains...

Variables on both sides of the equation are the name of the game in this video, and Sal's easygoing manner and thorough instructions make even complicated algebraic equations look like games. He warms up with two equations to demonstrate...

Sal adds a few more steps to these problems as he solves algebraic equations with two steps, though he states that "there's more than one way to do it." Those who become confused by increasingly complicated algebra problems on a test...

Elimination is another method for solving systems of equations, in addition to graphing and substitution. Sal's lecture is straightforward to understand, even for students who struggle with learning. By having a variety of options when...

Here is a challenging motion problem about two different length trains and how long it takes them to pass each other going in the same direction and opposite directions. At first glance, there doesnÕt seem to be enough information given...

This fourth of twelve units in a series continues the investigation of functions through equations and inequalities. However, the modular nature of the lessons in the section make this an excellent resource for any curriculum...

This first of twelve algebra 2 resources provides a broad review of many algebra 1 concepts through a number of separable lessons and labs. Starting with the real number system and its subsystems, the sections quickly but thoroughly...

In this third of a twelve-part series, the focus moves from using matrices to solving systems of equations with substitution and elimination, including more than two dimensions and variables in equations, and analyzing statistical data....

There's just something special about lines in algebra. Introduce your classes to linear equations by analyzing the linear relationship. Young mathematicians use input/output pairs to determine the slope and the slope-intercept formula to...
