We all know tides have something to do with gravity from the Moon and Sun, but if gravity affects the motion of all objects equally, then how come oceans have large tides while other bodies of water don't? It's because your mental...

Because of the chaotic way fingerprints develop and the multiplying effect of compound probability, it's basically impossible for any two fingers to have matching...

Today we're going to introduce one of the most flexible statistical tools - the General Linear Model (or GLM). GLMs allow us to create many different models to help describe the world - you see them a lot in science, economics, and...

A beautiful proof of why slicing a cone gives an ellipse.

Today, we're looking at measures of spread, or dispersion, which we use to understand how well medians and means represent the data, and how reliable our conclusions are. They can help understand test scores, income inequality, spot...

You’re on the trail of a werewolf that’s been terrorizing your town. After months of detective work, you’ve narrowed your suspects to one of five people. You’ve invited them to dinner with a simple plan: to slip a square of a rare...

With the advent of the Internet and social media, news is distributed at an incredible rate by an unprecedented number of different media outlets. How do we choose which news to consume? Damon Brown gives the inside scoop on how the...

Have you ever wondered why your shadow is longer sometimes and shorter others? It turns out it all has to do with that marvelous big ball of light in the sky; The Sun! This first series is based on 5th grade science. We're super excited...

Guitar masters like Jimi Hendrix are capable of bending the physics of waves to their wills, plucking melody from inspiration and vibration. But how do wood, metal, and plastic translate into rhythm, melody, and music? Oscar Fernando...

How to think about implicit differentiation in terms of functions with multiple inputs, and tiny nudges to those inputs.

Today we’re going to finish up our unit on data visualization by taking a closer look at how dot plots, box plots, and stem and leaf plots represent data. We’ll also talk about the rules we can use to identify outliers and apply our new...

Herein we explain that birds do not hibernate in lakes, do not migrate to the moon, but DO go on very unique journeys, which we humans have learned about in a variety of ingenious manners.

New ReviewIn this math video lesson, students analyze a graph with six plotted points and determine which point could be removed so the relation becomes a function. The exemplar solution models how to apply the vertical line test, showing that...

New ReviewIn this short math video, students learn how to graph a system of linear inequalities step by step using clear visuals and explanations. We begin with a quick review of how to graph a line in slope-intercept form. For the first...

New ReviewIn 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...

New ReviewWhen 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.

New ReviewIn this video we are going to explore how to graph a quadratic equation using vertex form using a easy, medium and hard example.

New ReviewWhen understanding how to find the inverse of a function either graphically or algebraically there is

New ReviewThis video explains three common methods for graphing quadratic equations (0:00). It covers using the axis of symmetry and vertex formula for standard form quadratics (0:23), the vertex form for quicker graphing (4:46), and intercept...

New ReviewIn this video, I provide five tips for graphing logarithmic functions, especially if you struggle with graphing logarithms. We'll cover how to graph logs and address common mistakes, including understanding asymptotes to accurately plot...

New ReviewIn this video I am going to work through how to find the extram of a function on a given interval
