Paul Andersen begins with a brief description of NASA discoveries related to Mars, Mercury and water. He then explains why water is required for life. He finally uses a simulation to show you why water acts as a wonderful solvent and...

In this episode, Hank goes over Reversible Reactions, the water dissociation constant, what pH and pOH actually mean, Acids, Bases, and Neutral Substances as well as the not-so-terrifying Logarithms, strong acids, weak acids, and how to...

Why is it that humans react to stimuli with certain behaviors? Can behaviors change in response to consequences? Peggy Andover explains how the brain can associate unrelated stimuli and responses, proved by Ivan Pavlov's famous 1890...

Paul Andersen explains pH as the power of hydrogen. He explains how increases in the hydronium ion (or hydrogen ion) concentration can lower the pH and create acids. He also explains how the reverse is true. An analysis of a strong...

The oldest light we can see comes from when the universe was less than 400,000 years old, so how can we study those first few moments of history?

The heat equation, as an introductory PDE.

A Simple Proof of Conservation of Energy

New ReviewWhen life gives you lemons...

In this math video lesson, students learn how to write the equation of a line that passes through a given point and is perpendicular to a given line. The visually modeled solution begins with a review of perpendicular lines, emphasizing...

In this math video, we will learn how to write the equation of a quadratic function given three points. We begin by recognizing that two of the given points are zeros, or x-intercepts, and use them to write the quadratic in intercept...

In this math video lesson, we will learn how to simplify numerical expressions with integer exponents. Students will clear negative exponents using the idea of reciprocal location, apply the product of powers property to multiply powers...

In this video we are going to focus on mistakes that students make when they need to solve a system of equation by graphing the system.

In this video I will show you step by step how to apply long division to a polynomial to the 4th degree by a quadratic binomial.

This video provides a step-by-step guide on performing long division with polynomials (0:00). The presenter emphasizes the importance of arranging terms in descending order (0:19) and demonstrates the process using an example, including...

While this may look like two linear equations we are actually working with a linear equation and a reciprocal equation.

In this video we are going to go over how to determine the other quadrants of the unit circle

This Student asked me to graph the radian in standard form so I decided to make a video about it how I like to approach it.

In this video we are going to work through a synthentic division problem to see how long it will take us to compled

In this video we are going to focus on the impact that transformations have on the square root function. In addition to that we will look at how to find the transformations of that function

In this video I take a trigonometric expression and multiply it by another trig expression.

When you need to graph the tangent function, not always does it need to be exact with multiple points. Sometimes we just want to know how to graph something quickly.

When you need to remember how to graph the sine and cosine graphs quickly there is one thing you should remember. In this video that is what I want to explore with you.

In this video we are going work on graphing a rational expression with 4 vertical asymptotes.

There are a couple of different techniques to factoring quadratics with fractions. In this video I am going to walk you through dealing with fractions to make factoring much easier.
