These second-order linear differential equations can be written in the form dx/dt = ax + by dy/dt = cx + dy Depending on the values of a,b,c and d, the dynamics will be very different! They can be characterized by finding the eigenvalues...

Here we show another way to graphically interpret first order ordinary differential equations (ODE's) in the form dx/dt = f(x). Rather than solve the differential equation by integrating, which is often impractical, it's useful to graph...

This video deals with nonlinear differential equations in the form: dx/dt = f(x) To find out whether a fixed point is stable or not, a linear stability analysis is done whereby the function is approximated as a line. If the slope of that...

Can you always pair an equal number of red and blue points with no intersection?

When teams follow these Group Problem Solving Steps, they are much more likely to reach effective, high-quality decisions and less likely to let ineffective decisions move forward. Thanks to research by Randy Hirokawa and his associates,...

In this video, you will learn how to write about the events in your imaginative narrative or fantasy story. You will learn how to write about the rising action leading up the the problem, describe the problem in detail, and stretch out...

In Part 2, Kevin provides a recap of the different conflict styles and presents the "STOP, THINK, TALK/LISTEN, CHOOSE" framework for conflict resolution. He emphasizes the significance of pausing, thinking about possible solutions,...

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 learn how to plot the solution on a number line to answer a standardized math test question. We will solve an equation by adding rational numbers. We will review the rule for adding number values with...

Short answer: Yes, drinking a lot of water will certainly change the pH of the stomach, but this amount is trivial. However, since your stomach is very acidic, to begin with, drinking water will not dilute it significantly. Also, there...

In which Hank discusses what intellectual property is, and how copyright is increasingly being policed by dumb robots that don't have very much to do with the law, but have everything to do with it just being REALLY COMPLICATED and there...

This video will show you how to embed seeds in agar plates so you can conduct seed germination experiments. This process is easy and the clear agar and petri dishes allow you to easily observe the seeds as they germinate. For a science...

We've all heard the terms acid and base. What do these mean? Don't just tell me about pH, silly. What structural detail makes a molecule an acid or a base? You don't know? Well, you'd better watch this then. You don't want to be...
