“Identify Extraneous Solutions” will review the different methods of how to test equations for extraneous solutions.

This video will explain and demonstrate how to simplify radical expressions.

Nobel Laureate Roger Penrose, University of Oxford, describes how, while he's not exactly aware of what exactly motivates him to write his popular books about physics, he clearly looks to Galileo as an inspiring role model.

Can physics help up develop better neural networks?

You will solve for the point of intersection of two linear equation problems with two variables.

Imperial College cosmologist Claudia de Rham describes her view of how reinterpreting Einstein's theory of gravity in terms of particle physics gives a more coherent and elegant picture of the forces of nature.

Celebrated polymath and mathematical physicist Freeman Dyson (IAS) describes why he is not a reductionist.

Duke neuroscientist Miguel Nicolelis describes how all human knowledge, even matters such as basic physics that seem completely independent of human experience, naturally depend on the nature of our brains.

Nobel Laureate Roger Penrose muses on how, despite being aware of the potential cosmological constant for many decades, most physicists were shocked when dark energy (commonly associated with such a constant) was observationally detected.

Nobel Laureate Roger Penrose (Oxford) tells us why he is sceptical of the inflationary theory of cosmology.

Nobel laureate in Physics David Politzer (Caltech) uses a banjo to demonstrate how octaves and harmonics arise from vibrating strings.

Nobel Laureate Roger Penrose, University of Oxford, describes why he believes that inflationary cosmology doesn't explain the mystery of why the universe began in such an unlikely, very smooth state, arguing that had it started out...

Celebrated scientific polymath Freeman Dyson, Institute for Advanced Study, describes how he is "more interested in the details than the big picture", and explains why he thinks that it is vital to not just search for overall equations,...

This video will discuss examples to find approximate solutions by graphing, using technology. Equations of the form f(x) = g(x) will be solved, where f(x) and g(x) may be linear, polynomial, rational, absolute value, exponential, or...

Multi-Step Equations demonstrates how to solve multi-step equations by using the distributive property to combine like terms on one side of an equation.

Two-Step Equations shows how to write two-step single variable equations by using verbal models.

“Solving Multivariable Equations” will instruct you on how to mold an equation to solve for a needed variable.

“Motion Terms and Equations” reviews key vocabulary associated with motion, as well as equations used to calculate the various aspects of motion.

“Systems of Equations” will explain how to tell whether two lines intersect, and if they intersect, how to solve them.

Nonlinear Dynamics mini-series Part 1: • 1.0 A better way ... Part 2: • 2.0 A better way ... Part 3: • 3.0 A better way ... This video shows a formal proof behind linearization for 2D flows: dx/dt = f(x,y) dy/dt = g(x,y) Step 1: Find...

Equations with Fractions demonstrates how to solve one-step equations by using reciprocals when the coefficient of the variable is a fraction.

In this video, you'll learn different ways to make 5 and how to write addition equations to match!

In this video, the teacher explains how to solve a system of linear equations using the method of substitution. The viewer is given a question to solve and is guided through the steps to find the solution using drag and drop activities...

In this math video we will solve a two part question about a proportional relationship with a table and an equation. We will begin by understanding the table and finding the unit rate. We will find the change in each column as we...
